Rasmussen lost me when he wouldn't pick a winner in the Brown vs. Coakley race, when most every other pollster had Brown winning.
PPP (although they tilt left) is more accurate and consistent in their polling methodology, IMHO. Also, a cumulative analysis of polling results is required, some folks look at just what this one flawed prognosticator publishes and take it as truth. It isn't.
Actually, he was the first pollster to see that race narrowing. True, he didn't poll the week-and-a-half before the election (not sure why), but he did detect a much closer race before anyone else did.
PPP is hit and miss.
Ras stated firmly that nothing had changed in the past week and they were holding with the numbers that stated that coakley would win... check the archives... he officially offered no poll that week... but he vocally made the statement above. Having said that... these numbers may be dead on.

The important thing to remember is polls have a margin of error and things change day to day (it’s only late May we have a way to go).
The polls right after the gay thing showed the biggest lead for Romney.
Almost every poll of likely voters in the past few weeks that I’ve seen has shown Romney up at least little. And given that undecideds can be expected to break away from the incumbent I believe if the election were today Romney would win, it would surprise me if he didn’t.
Rasmussen is a good pollster, but this is just ONE poll, if 5 in a row show Obama ahead then maybe I’d worry.
He’s a top one to look at but others are also good.
PPP is accurate also when they try to be, you never know when they have an agenda. Like a recent poll they did showing Carol Che-Porter leading in a NH rematch against Congressman Guinita. Give me a break. The Bass/Kuster rematch they have as a tie, that I can believe.
Other recent polls in the RCP list
A poll of registered voters showing Obama up only 3 from biased ABC/WA Post. And the Gallup tracking poll of registered voters, tied. Gallup is one to watch but you have to adjust for them using registered voters. Why anyone uses registered voters is beyond me. One of my brothers is registered, he has never voted.
Fox news continues to have really really crappy polling. Romney at 39%, okay Fox stop using Geraldo’s weed.
I liked the polls from the French election, they factor out or assign all the undecideds.
