Casey's approval rating remains in the low 40s - http://www.pittsburghlive.com/x/pittsburghtrib/news/regional/s_716843.html
"(Casey) went into Washington with all kinds of ideas, but once he got elected, I feel like we never heard from him again," said Joyce Keith, 57, a Democrat from McKeesport.
I actually was cornered into meeting and shaking hands with Casey today outside of Toomey's reception. I'm sure you can just imagine how weird that was for me. 
He was actually literally two feet from Santorum and they awkwardly bumped into each other. Surprisingly, they are apparently very friendly to each other.
Two senators from the same state, they almost need to be to bring home buck$. That isn't always the case, of course, but it helps.
Oh, and his disapproval rating is only 27%. I'd like to know how much of the 30% undecided is actually "mixed opinion" vs. "no opinion". If I had to hazard a guess I'd say largely the latter.
