FYI Rasmessen has a 5 point race right now in PA.
Rasmussen seems to me to be hedging a little conservative (in terms of numbers, not politics) during the Romney surge. It's unlike the usual landscape to have many other polls moving in favor of the Republicans as much or more than Rasmussen. It's unusual for my own assessment to be 3 points greater than Rasmussen's.
And his piece today was blather. FR thread here.
Whatever the nature of the Republican win, it will be interesting to look back on Susquehanna's polling vs actuals, because they have been really cocky, and I agree with them.
