Public Policy Polling released a spate of polls last night, all of which you can find on their blog. There’s absolutely no good news in them for Democrats and their supporters. They showed Bob McDonnell holding a comfortable 56-42 lead in VA-Gov, Chris Christie surging late to a 47-41 lead in NJ-Gov, Question 1 winning in Maine (that would invalidate their gay marriage law) by 51-47, and Doug Hoffman up big (54-38 in a two-way race) in NY-23.

The unifying thread here is that all of the polls assume a more conservative electorate than similar polls released around the same time frame. For example, a Siena poll showing a deadlock in NY-23 had Barack Obama with a 59% approval rating among likely voters. PPP has him at 39%. In NJ-Gov and on Question 1 the electorate is more Republican in PPP’s polling as well. VA-Gov is pretty much in line with other averages.

These are assumptions made by pollsters based on voter intensity and modeling. PPP is either right that Republicans are far more excited to vote this year, or weighting that too heavily. Either way, we’ll know by Tuesday night.
