This is kind of fun. The three most endangered GOP incumbents in Pennsylvania -- Mike Fitzpatrick, Jim Gerlach, and Curt Weldon -- are all competing with each other to prove their undying disloyalty to Bush. How? They're all pointing to what has become a bragging point in this campaign: their low scores in the party-loyalty ratings compiled by Congressional Quarterly. And the winner is...Fitzpatrick, who's apparently the third least loyal Republican among all 231 GOP House members.
