Electoral Math Charts Updated


It's time once again to take a look at the Electoral College math from state-level polling. Nationwide polls are not completely meaningless, but they are pretty irrelevant -- because that's not how we elect a president. You have to win enough states to get more than half the electoral votes in the Electoral College. While many would like to change this system, it's what we've got for the 2008 election, and so looking at the state-level polling is much more important to figure out where the race is right now, and what the trends are.

The last time I wrote about this, I listed some caveats which bear repeating here:

A few caveats, first. These graphs were created using data from the electoral-vote.com website, and I can't personally vouch for their accuracy. These are all state polls, and not national polls. Some local pollsters are better at understanding their state's demographics than the national pollsters are, and some are not. And sometimes everybody gets it wrong (see: New Hampshire Democratic primary, for instance). Polling itself may be missing people with cell phones (and no land lines), and may also be missing new voters (many polls only look at "likely voters," defined as those who have voted previously). And these state polls are only updated sporadically, meaning some of this information is months out of date. So I'm not saying that these polls are going to reflect perfectly the outcome of the vote, in other words, but then no poll can really make such a claim. But you have to use the data available, and the electoral-vote.com website has one of the better presentations of available data, so I chose to use their figures.

OK, enough caveats. Polls aren't perfect, I think we all understand that. But they can be instructive nevertheless.

First, let's start off with the percent each candidate has in the Electoral College (based on current polls, and assuming that even very close states break the way the last poll indicated). McCain is red, Obama blue, and ties are white.

EVpercent01sm

There has been some activity since the last time we looked at this (7/21/08). Obama lost some ground initially, and McCain gained some; but then there were three important states that were tied for a while (Florida, Missouri, and Virginia), which came at McCain's expense. The tied states swung one way or another, and the race has since tightened up. Initially, both Obama and McCain made gains, but this was partly due to an outlier poll showing Obama barely ahead in Florida. Florida has gone back to McCain, which is the most recent movement in the chart. Percentage-wise, Obama is down from the high 50s to the middle 50s, and McCain has improved from the high 30s to the middle 40s. Obama still leads in outright electoral votes, 289 to McCain's 236 (with Virginia's 13 still tied).

While Obama is down from where he was before, he can improve his standing considerably by flipping Ohio back into his column, with their 20 electoral votes (in the last Ohio poll, McCain is up 45 to 43).

Let's drill down into each candidate's numbers to see their relative level of support. First, John McCain.

McCainEV01sm

As always, these are divided into Strong (10% or better lead in the polls), Weak (5% or better) and Barely (less than 5%).

McCain's Strong support got a little better, moving from 86 electoral votes to 97. Since July 21, McCain has lost Alaska from this column, and gained Mississippi and South Carolina.

McCain's Weak support went from 95, up to 98, then stepped down to as low as 57 before bouncing back to stay exactly the same at 95. So the overall gain for fairly safe states for McCain (Strong plus Weak) goes up by 14 electoral votes, to land at 192 total.

McCain also made progress in his Barely column, mainly due to snagging both the Dakotas, Montana, and (the big one) Ohio. McCain's Barely total goes from 18 to 44. While the total is still short of the 270 he needs, that's a pretty disturbing trendline for the last few weeks.

ObamaEV01sm

Barack Obama's chart shows some hiccups in the weakest of his support among the Barely states, but a fairly solid and steady amount of Strong and Weak support since the last time we looked at these charts. Although, again, the Strong support seems to be softening a bit into Weak, which is a disturbing trend to keep an eye on.

Barack's Strong support went from 211 to 185 in the past few weeks. He lost Minnesota, New Hampshire, and Massachusetts. But I still feel pretty confident that two of these states will be blue on Election Day, and the third (NH) is the smallest one, with only four electoral votes.

However, Barack's Weak states picked up the slack, going from 35 to 58 electoral votes, which is why the line you get when you add the two together has stayed almost perfectly straight the past few weeks. Weak plus Strong for Obama went from 246 to 243 overall.

The real movement in Barack's chart is in the Barely states. Many battleground states have gone back and forth, and so this is the most volatile area to make predictions. Part of the reason for such a big swing in this was Florida going for Obama, then back into McCain's column (since Florida has 27 electoral votes, it shows up in a big way on these charts). Barack went from 66 to 46 in the Barely states since last time we checked. Overall, this caused Obama's number to come down from 312 to 289. Which is still more than 270, even without Florida and Virginia, but the trends need to reverse or at least flatten out for Obama to successfully hold these numbers.

Since this is running a bit long here, I'm not going to make predictions this time around, but rather just identify how I personally divide the states up (which relies on more than just data from these charts).

 

Safe States

I'm going to take New Hampshire away from this column, as support seems to be weakening for Obama there. But to replace it, I'm going to move Oregon into the "Safe" category for Obama. The latest poll there showed him with a nine percent lead over McCain, so this is a fairly safe bet. Obama's total Safe list of states: CA, CT, DC, HI, IA, IL, MA, MD, ME, MN, NJ, NY, OR, RI, VT, WA, WI. That adds up to 17 states (and 214 electoral votes) in Obama's "Safe" category.

States I would call as "Probable" for Obama had some movement as well. Oregon moves up to Safe, and New Hampshire comes down from Safe. For now, I'm also moving Pennsylvania into Probable for Obama. Obama's Keystone State support has wobbled, but appears to be firming up a bit for him. This is important, as Pennsylvania is a much-needed state for Obama. So, Obama's Probable list (DE, NH, NM, PA) adds four more states and 33 more electoral votes, for a total between Safe and Probable of 247 electoral votes, just 23 shy of the 270 needed to win.

John McCain's Safe states have added Mississippi and South Carolina, for a total of 14 states, but only 97 electoral votes (AL, AR, AZ, ID, KS, KY, LA, MS, NE, OK, SC, TN, UT, WY).

McCain's Probable states lost two (MS and SC) which moved up to Safe, and lost Florida to being a Tossup (McCain's poll support has wavered here). Although Florida is a heavyweight, I am also adding another heavyweight to Probable for McCain -- Texas. So McCain's Probable list (AK, TX, WV) has only three states but a whopping 42 electoral votes.

Of course, this still puts him way behind when you add Safe and Probable, which only gives McCain a total of 139 electoral votes. That is 131 votes shy of the 270 needed to win.

So Obama's still got many more ways to engineer a win. Obama is down only 23 electoral votes, while McCain still pretty much needs to run the table to get the 131 he needs.

 

The battleground states

This leaves 13 states as the battlegrounds, which share 152 electoral votes between them (total adds up to 51 states due to Washington, D.C.). These are broken down into "leaning" states for Obama and McCain, and the "too close to call" Tossup states.

Tossup states leaning Obama right now are Colorado and Michigan. Since last time, Pennsylvania firmed up for Obama, moving to Probable. Montana dropped down to "too close to call," but Colorado moved up from the same category. I would really love to move Michigan to at least Probable for Obama, but so far the polls haven't reflected strong support for him here. Michigan is another crucial state for Obama to win, so it's one to keep an eye on. And while Colorado is definitely trending Democratic, the polls are still showing only tepid support so far for Obama. Maybe the Democratic convention (in Denver) will help, later this month. These two states add up to 26 electoral votes leaning Obama's way.

Tossups leaning McCain are: Georgia, Missouri, North Carolina, and South Dakota. Texas moved up into Probable for McCain, and he picks up Missouri from the "too close to call" category, at least for now. McCain's Georgia poll numbers are good, but not great (and there's always favorite son Bob Barr in the mix there). But while any of them could go Obama's way eventually, they're all leaning McCain as of now. These four states add 44 electoral votes, cutting what McCain needs to win down to a (still formidably big) 87 electoral vote shortage. As I said, McCain really needs to run the tables to have any sort of chance of winning, as things stand now.

As far as the rest of them go, they're all too close and too volatile for me to call one way or another. The final seven battleground states are: Florida, Indiana, Montana, Nevada, North Dakota, Ohio, and Virginia. Between them they share 82 electoral votes. Colorado moved to Obama, but Montana moved from Obama to here. Missouri went towards McCain, but Florida came from McCain at the same time.

Overall, things still look very, very good for Obama. But the trendlines are indeed a bit worrisome.

 

[Blatant website plug: ChrisWeigant.com has just added a new 2008 Electoral Graphics page with a constantly-updated electoral graph and electoral map. These are different graphs than the ones I use here, and are created by Samuel Minter of Abulsme.com. The data gathering and methodology he uses is superior to what I have used, as he averages the last five state polls for every state (which smoothes out the outlier poll numbers). I encourage you to check this page on a daily basis to see how the trendlines are moving, right up to the election.]

So it really comes down to Colorado (and not Ohio as I had thought a few weeks ago)?
12:09 PM on 08/09/2008
Posting this here, as it may provoke some interesting commentary.

Charles Blow is one of 2 black columnists on the NYT. He raises concerns
about the 'statistical tie' between Obama & McCain, which exists only in
some estimates of the Popular vote, It seems reasonably clear that Obama
leads in estimates of the Electoral vote, which is what really matters.

Now, Mr Blow's concern is mainly racism among voters. Certainly a valid one,
but it is used here to perpetuate a myth that the election 'seems' closer than it
may actually be, in the arguably irrelevant popular vote.

Why are we not seeing MSM discussion of electoral vote standings?

-------------------------

NYT - August 9, 2008 - Racism and the Race - Charles Blow

This is supposed to be the Democrats’ year of destiny. Bush is hobbling out of office, the economy is in the toilet, voters are sick of the war and the party’s wunderkind candidate is raking in money hand over fist.

So why is the presidential race a statistical dead heat? The pundits have offered a host of reasons, but one in particular deserves more exploration: racism.

Barack Obama’s candidacy has shed some light on the extremes of racism in America — how much has dissipated (especially among younger people) and how much remains.

According to a July New York Times/CBS News poll, when whites were asked whether they would be willing to vote for a black candidate, 5 percent confessed that they would not. ...

I'm very surprised to see Michigan as a toss up state or "lean dem" on different sites. The only chance McCain has of winning here in Michigan is by picking Romney (native son) for VP. But even then, I'll have to see it to believe it. People in Detroit, especially, are hurting and need real solutions from a candidate - not more of the same. Obama has some very specific plans and ideas on how to get a lot of people back to work here; reopening factories with government loans to build electric cars and green energy equipment. McCain spent his time here at the nuclear power plant, lying about Obama's tire inflation "energy plan".

I sincerely hope MI is solid in Obama's column.

Romney might indeed be a wild card. It might split between how many Michiganders remember the Rambler, and how many do not (or for that matter, how many even remember AMC). Laugh if you will, but this may be an important demographic split in the electorate. George is well-beloved, but can Mitt count on the same support? Time will tell...

Chris:

Apparently Obama has been spending big advertising dollars in Georgia and North Carolina. If he asked me (and so far he hasn't), I would recommend spending little money in GA and NC and instead focus on the Tossup States Leaning Obama and the Too Close To Call states which you have identified.

Is that a good use of his advertising dollars?

[Love your login name, by the way]

GA could swing by the presence of Barr. NC could swing on its own, due to high black turnout. So while maybe his ad dollars could be spent elsewhere, I would have to give the benefit of the doubt to Obama's media folks at this point...

Given the state of the economy and foreign policy it should be a clean sweep for Obama. One of the reasons that it is not is the PUMAs. See, e.g., http://www.breitbart.com/article.php?id=080806194222.o84em5uv&show_article=1

I don't understand why HRC doesn't put a stop to it -- persona phone calls to the ten or so ring leaders followed by a short press statement should do it.

Gotta disagree with ya' "mildmannered"

In the first place, whoever thought up this PUMA name did a disservice to the party and Sen. Clinton both. Now there's a handy and mean-spirited tag for Sen. Clinton's suporters that bears no relation to 99% of them.

I supported Sen. Clinton because I believed her to be the superior candidate. (Still do)
Democratic voters decided otherwise...... and not by much.

The REASON for that small margin was that both Clinton and Obama were and are EXCELLENT candidates, with similar views and formidable political and policy skills.

I'm very enthusiastic about an Obama presidency, and he'll have my full support, as I'm confident he'll have the support of the Clintons themselves and all true Clinton supporters.

No one who honestly supports what Bill and Hillary Clinton have stood for over the course of 40 years is going to vote for more war, more predatory economics, more head-in-the-sand environmental and energy policies, continued racism in the criminal justice system, more radical neo-conservative judges....(clearly I could go on)......

Further.... damn few Clintonites can fail to be excited by the prospect of a highly inspirational figure like Obama restoring the US to a position of respect around the globe.

Anyone who calls themself a progressive..(I've never been ashamed to call myself a LIBERAL) can see that Obama has the POTENTIAL to be one of the truly GREAT leaders of this or ANY century.

......time will tell

Interesting information. On a personal note, I was amused to realize that all the states listed in McCs column are places I would either never want to visit, or visited and did not enjoy. I wonder what that means? Nothing, I guess. But here's a shout out to O people in PA: We have to work our back ends off to get PA firmly in the O column!!!!

Now, now, let's not get personal here! While Wyoming and Utah are two of the reddest states on the map, they both are beatiful and awesome (in the original literal meaning of the word). To say nothing of Alaska (although it's looking a wee bit purple these days). And don't forget, red states have some pretty thick-skinned Democrats holding down the fort in their own ways! I've heard from Democrats all over the country who, even though they know their state will likely go McCain, are just as enthusiastic over this election as we are in California. So give them a break!

While the trendlines this time around aren't great, the line I watch closest is the one you get when adding Strong and Weak. It's the top of the middle section of the McCain and Obama graphs. Obama's line is pretty steady at just under 250, while McCain hasn't topped 200 since June. So Obama's a lot closer to the finish line by over 50 votes -- keep reminding yourself of that...

Just like there are speculators for driving oil prices, there are speculators for this election. You people believe everything to read and hear, which is why we are stuck with this administration we have now. You know what the ReThugs are doing and you apparently are falling for it once again. We have 3 debates coming up with perfectly fair moderators as I have seen before.

So, lets not throw the baby out with the bath water. It's not said and done until the debates. The fact that you and others base your opinions on something that can be manipulated shows the level of ignorance this country still has to deal with along with race.

Until that happens, it will be right there festering under the skin as always waiting to come out once again. That white house and much more was built off the blood, sweat and tears of black slaves. This backwoods mentality must end with this election. It's time for a change in politics, because the last eight years proves that we now need some intellect as well as capability running this country.

We need someone that doesn't breathe war 24/7 but, is willing to speak to our enemies with diplomacy and not bullism; then maybe, we can get something done other than fighting. Our economy is shot to he$$ and we need to be focusing on reviving it and not on trying to fend off war finatics that we have prevoked without merit.

Aw, shucks, now I'm blushing...

My motto is: "Reality-based political commentary" and that's the standard I hold myself to. Um, except on Fridays, when I open a can of whoop-ass on the Republicans... but, hey, four out of five days a week isn't too bad!

I've long said I'm amazed at how many bloggers don't respond to intelligent commentary, both pro and con. I've learned a lot from my commenters so far, because they're not always an echo chamber. And the best way to get opposing viewpoints, sometimes.

Thanks for commenting!

it is certainly reality-based commentary--which, in and of itself , is rare these days. but more important (i dare say) to most of us reading and commenting on this blog is that we learn something. you have reached some provisional conclusions and we see how you might have reached them.

continue the good work--even if, the latest sex scandal has knocked you off the main page.

What about the Nader & Barr affect? I while ago the news was that when Nader and Barr were added to the poll options, Obama's lead increased significantly.

I have not seen an update to that in at least a month.

That could be very relevant.

While third-party-including polls are all but unavailable on the state level, Pollster.com does have a chart for how it's tracking on the national level. You're right, Obama's lead widens.

http://www.pollster.com/polls/us/08-us-pres-ge-mvoand3s.php

But the data points are fewer, as pollsters don't usually ask. I wrote about this a few weeks ago:

There's something that I don't think the pundits or the bloggers are looking at - at all - as a means of gauging the race: gambling odds. Sportsbook.com is now giving Obama 2-5 odds for winning right now with McCain at 7-4. The presidential election may not be the Super Bowl, but in fact the outcome is likely much more predictable due to the lack of huge surprises (I don't think Illinois is going to fumble and suddenly go Republican).
