“or maybe he is just worried about the primaries”
Probably. He is trying to look “conservative” and will likely continue to do so, up until the primary, in order to win re-election, and then, once he does, go back to his traitorous RINO ways.
We know who he truly is! To the Republicans in Pennsylvania: DO NOT LET HIM WIN THE PRIMARY!!!!!!!! VOTE FOR PAT TOOMEY!!!!!!!!
I say enjoy it while it lasts, and still vote for Toomey in the primary!
