Thos race and Kentucky show an interesting trend. The vast majority of the movement in the polls comes from either Toomey or Paul. Sestak's number and Conway's number generally remain in the low to mid forties. To some extent, that reminds me of Casey's race with Santorum. Santorum never got past 42 or 43 in the polls. When one showed the race close, it was due to Casey's number being lower.
Interesting comparison. Of course Toomey won't get 59%, he doesn't need to. He will get 52%-54% and that was what Casey was going to get before Santorum's second leg down in the polling in Sept and October.
