Is the Not McCain Party being born in NY 23?

Some of the most prominent names in national Republican Party politics are lining up against the GOP nominee in a key upstate New York House special election, the latest being former Pennsylvania Sen. Rick Santorum, who weighed in Friday.

In endorsing Conservative Party nominee Doug Hoffman in the Nov. 3 contest, Santorum joined former Alaska Gov. Sarah Palin, former House Majority Leader Dick Armey, Minnesota Rep. Michelle Bachmann, former Tennessee Sen. Fred Thompson, and former presidential candidate Steve Forbes, all of whom announced their backing for the conservative third-party candidate this week.

Minnesota Gov. Tim Pawlenty suggested Friday that he might be the next well-known Republican to break with the party establishment and support Hoffman. When asked about the race Friday during an interview with ABC, he expressed frustration with GOP nominee Dede Scozzafava and said he will “probably” endorse in the race.

Scozzafava, a state assemblywoman who supports gay marriage, abortion rights and has a close relationship with leading labor officials in her region, has been the target of sustained criticism from conservatives who claim that she is so liberal that they cannot in good conscience support her candidacy. As evidence, they point to her unofficial endorsement from the leading liberal blog Daily Kos.
