in 2008, (R)ASSmussen consistently showed McAnus ahead of Barack Obama...until the eve of the election, when they made a major course correction and called it for President Obama - just in time to garner the 'most reliable' title.

for not doing my own research. Thanks for correcting my mistaken assumption.

CHeck out RCP.

Notice that they only claim this "accuracy" on their last national poll. Maybe do more research before posting.

2008 - rated highly reliable; 2010 - Nate says nuts to Ras!

When assessing polling accuracy, there are various ways of measuring. In 2012, when you have polls that consistently are outliers, like Rasmussen--which were some of the worst polls in the 2010 cycle, it certainly defies credibility that anyone would still consider them as one of the more accurate pollsters.

Not sure @ sustainability of various pollsters. I don't even see PPP in the 2008, nor 2010 (I think?) pollster listings?

and comparing to this list.

Ras has O up 5 in PA right now. Good!
