Well their last poll was way back in March (unless it is missing from this list I am looking at), it would have been helpfull if there was a late May poll by them as well to see where it was post primary.
Toomey has been stagnant in this poll while Sestak keeps rising, month after month. I really think this will be a difficult for Toomey to pull off.
Keep in mind though the primary occured in between the last Quinnipiac Poll and this one. Thus that could be the consolidation of the Democratic vote behind Sestak. For all we know, Q would have had a 5 point Sestak lead post primary. The highest Sestak has reached was the 46% reported by Rasmussen which has since fallen back. I think there was likely a similar pull back to the low 40's in most firms (and high 30's according to Rassy) were all polls conducted at the same time with there different methods. This would leave Sestak on firmer ground because of the end of the primary, but not as high as the intial post primary bounce. We will probably start to be able to tell for certain, once August rolls around, whether one or the other is consistently gaining momentum.
