Unlikely Voter

Should the Republicans get lucky and take the Senate in November, Patty Murray’s is the kind of seat they will have to win. Washington is friendly territory for Democrats and 2010 should be no exception. However, a poll from late Friday suggests that she may be vulnerable to Dino Rossi and only to the former candidate for Governor.

More confusion is ahead as we look at Rasmussen’s latest treatment of the Colorado Senate race.

Yesterday we looked at a poll from Public Policy Polling, but today we have a new poll from Quinnipiac University.

Amusingly enough, while we’ve seen Quinnipiac overcount Democrats in Ohio, their results for Specter and Sestak come in just under PPP’s findings.

Yesterday Public Policy Polling came out with fresh results for the Pennsylvania Senate race. Unfortunately they didn’t poll the primary race between incumbent Democrat Arlen Specter and challenger Joe Sestak, it turns out not to matter much just yet.

Pat Toomey, Republican challenger, leads both men at this point.

If we look at a series of five polls of the Wisconsin Senate matchup between Senator Russ Feingold, Democrat, and former Governor Tommy Thompson, Republican, we find a broad range of results.

On no news can we really expect the race to move 16 points in one week? Some of these have to be wrong, but will we ever know which?

When I see people, and particularly conservatives, discussing why one poll is better than another, I see the sample pool frequently cited as a reason for favoring one or another. Specifically, some poll watchers insist that any poll not filtered for likely voters, instead of just registered voters or even adults, is not useful in a political context.

The dirty secret is that not all likely voters are created equal. Every pollster has his own secret sauce, and we have to be careful when trusting that kind of filtering. It might not be what we expect.

Rasmussen Reports has a new Nevada Senate poll out, and the results are looking terrible for Harry Reid. The Democrat is looking likely to be the second consecutive incumbent floor leader for his party to be voted out of office.

Conventional wisdom says incumbents below 50 are vulnerable. Well, two of the three Republicans running to replace him are now above 50, and the third is at 49.

USC and the LA Times polled some of the major California statewide races. The results, provided by pollsters Greenberg Quinlan Rosner and American Viewpoint, seem generally in line with what we’ve seen so far: Campbell and Fiorina are in a close primary race, lagged by DeVore. Boxer can’t reach 50. Whitman cruises in the primary.

The big news to my eye is that Jerry Brown has fallen behind.

It’s late; I spent a lot of time preparing my nationwide modeling software, but here’s a quick look at the Arkansas Senate race, per Rasmussen. It’s a mess.

Rasmussen Reports has a new one on the Ohio Governor’s race. Kasich 46, Strickland 45, MoE 4.5. 54% chance Kasich is ahead according to my model, down from the 80s a couple of weeks ago.

This is more consistent with the previous trend and seems to confirm the RealClearPolitics theory that Quinnipiac has a few points of bias toward the Democrats in Ohio polling.
