I wish the poll had been conducted after the start of Santorum's book tour, so we could determine whether he's winning any hearts and minds, but I'll still take these late-July results as good news:

Casey Keeps Double-Digit Lead in Pennsylvania

Many voters in the Keystone State are willing to elect Bob Casey to the United States Senate, according to a poll by Strategic Vision. 51 per cent of respondents in Pennsylvania would vote for the Democrat in a head-to-head contest against Republican incumbent Rick Santorum....

Support for Santorum is at 40 per cent. Two per cent of respondents would vote for other contenders, and seven per cent are undecided.

Onward to victory....
