The trend for Mitt is very solid right now, and that’s a big deal. I’m not thrilled with going into Penn, but the Romney team is smart & their internal polls must be showing a REAL shift there otherwise I doubt they would go there.
The Susquehanna Poll showing Romney leading +4 has a D+6. That's simply not realistic in the Commonwealth. If we could get to an enthusiasm gap like 2010, Romney would win (Toomey won by 1% I believe, I can't recall Corbett's number in the gubernatorial.) But we aren't going to get there. It will be MUCH closer than 2008, but I think it's a waste of time unless R/R have some internals with D+8 or D+9 that show them something we don't know about. Even so, if R/R has PA, they also have WI, IA and CO, and they probably also have OH, in which case spending money in PA still doesn't make sense.
