Tuesday Polls On Clinton's Do-Or-Die Contests

Astonishingly, there is still no polling data for a number of the primary contests looming in the next few weeks, though Survey USA corrected the most glaring of these omissions today by releasing the first public survey of Oregon, which votes on May 20th:

Barack Obama leads Hillary Clinton 52 percent to 42 percent. He is the one who benefits from a very large gender gap (+37 percent), as he leads by 30 percent among men.

Oregon's voting is conducted entirely by mail, with all the ballots counted the night of May 20th. That could create a different turnout pattern than what we have witnessed in other states. Another important fact about Oregon is that it holds a closed primary in which only registered Democrats can vote. This could be crucial for the Obama campaign, since one of Clinton's main arguments against him is his weakness among registered Democrats and his reliance on independents to win primaries; if Obama maintains a strong lead in Oregon, expect his campaign to use these numbers to counter Clinton's criticism.

Meanwhile, Clinton's main preoccupation is the April 22nd primary in Pennsylvania, for she doesn't have much to expect from any May states if she cannot hold her own in the Keystone state. All the polls over the past week show a dramatic tightening of the race, with Obama even leading in one of the polls and tying Clinton in a second. Today, three new polls from the Pennsylvania show very differing trends:

* Quinnipiac's second poll in six days shows yet another tightening, with Clinton's lead now down to 6 percent: 50 percent to 44 percent. The margin last week was 50 percent to 41 percent. Looking at the shifts among internals, there is no particular group who has moved more than others.

* Rasmussen's survey brings good and bad news for Hillary: She is leading by only 5 percent, 48 percent to 43 percent. But this margin has remained stable in the past week, making Rasmussen the first institute to release a poll without movement away from Clinton.

* And then we get the surprise: SUSA's new survey shows Clinton jumping back up to a very significant lead, 56 percent to 38 percent. Last week, Clinton was leading by 12 percent (so SUSA never went in the low ranges that other polling institutes are showing).

* SUSA points to a lot of groups that shifted in the past three polls over the past months (finding shifts among men and Southeast PA voters especially significant), but concludes that "The complete absence of movement among whites and among women is striking. Among white voters, Clinton polled at 61 percent in all three tracking polls. Among women, Clinton was at 62 percent a month ago, 62 percent last week, and 61 percent today."

These three polls confirm that the run-up to April 22nd will be significant, and that the debate next week could be crucial to the results. It goes without saying that a mid-single digit lead is much less than what Clinton needs to win by on April 22nd -- and there are too many polls showing the race to be trending against her for Hillary to be comfortable. But at least the SUSA poll suggests that (just as in Ohio) Clinton has not lost her upward potential and could recover enough of the ground she has lost lately to survive beyond Pennsylvania. The Obama campaign, however, is rapidly gaining confidence in its Pennsylvania numbers and this could lead them to invest even more in the state than they had planned. They do not have to believe that they will win the state, just that they will make a Clinton victory as thin as possible.

Finally, the last primary poll comes from North Carolina, where PPP has found Obama leading Clinton 54 percent to 33 percent. This is the same margin he posted last week. That the margin hasn't moved can certainly not be held against him given that it's a massive lead.

Pennsylvania, Oregon and North Carolina vote on three different dates; all three Election Days could mean instant death to the Clinton campaign. Clinton has to win Pennsylvania convincingly and she has to post great results on May 6th and May 20th. It seems to me that Clinton can survive without winning North Carolina and Oregon (as long as she wins Indiana and Kentucky comfortably) but she has to keep it close in both of these states -- and right now it doesn't look like she is managing to do that, at least in North Carolina.

General election polls: Washington and Alabama

The day's two general election polls come to us from (who else?) SUSA and Rasmussen:

* In Washington, SUSA comes out with Obama leading McCain 51 percent to 44 percent, while the Republican edges out Clinton 46 percent to 45 percent. McCain gained against both Democrats in the past three weeks, when another SUSA poll showed him trailing Clinton by 5 and Obama by 11.

* In Alabama, Rasmussen finds McCain leading Clinton 51 percent to 40 percent and Obama 55 percent to 37 percent. McCain's favorability rating (60 percent) far distances that of Clinton (46 percent) and Obama (39 percent).

While no one expects Alabama to be anywhere on the list of competitive states in November, it is worth pointing out that Bush won 63 percent to 37 percent in 2004. As for Washington, it is a state both Kerry and Gore had to worry about but ultimately carried more comfortably than neighboring Oregon -- so this time Democrats better hope to take a firmer control of the state's 11 electoral votes.
