A few quick updates on the poll data we track on races for the House of Representatives:
First, as of last night, we now have charts available for all 84 House districts for which we currently have polling data. Clicking on a link for any House district on our House map and national summary table now takes you directly to the chart for that race, just like the links on our Senate and Governor maps. This latest update means that any our 84 House district charts,** like the one from can be embedded on your blog or website using the new "embed Chart feature" (see yesterday's post for details).
Second, an apology for the slightly slower pace of blog posts over the last 48 hours or so as we worked to get these new upgrades and features up and running. I have also been spent a lot of time the last few days crunching my "big-spreadsheet-o'House" and will have a more in-depth review of the available polling data later today. For those who cannot wait, you can find the abridged version in our Slate House Election Scorecard updates on Tuesday and Wednesday.
Finally, a quick update on a bit of anecdotal evidence I discussed last Saturday. There is one source of polling largely out of public view - the internal polls conducted by the campaigns and party committees. Some of these get released, but typically only when they show good news for that particular campaign. So one indirect measure of where things stand is which side is releasing more of its internal polling, and by that measure the Democrats are a lot more confident: Since Labor Day, Democrats have released 54 internal polls for House candidates logged into our Pollster.com database, Republicans have released only 13. And that confidence has not abated in the last two weeks. Since October 15, Democrats have released 21 internal polls, Republicans only 2.
**Unfortunately, many of the House races have only a handful of polls. As of this morning, roughly half of the districts in our database have three or fewer polls, and that will make for a very sparse looking chart. Keep in mind that the trend line represents the average of the last 5 (or fewer) polls at any given point in time. So for the first few polls in the series, the lines may draw in ways that seem a little confusing.
