The guy switched parties. It happens. The only thing to do now is focus on finding a good candidate to give him a solid test in 2010. “The most conservative candidate who can win” is the rule of thumb and I think there are Republicans in Penn who fit the bill. Pat Toomey may or may not be that guy (presently, he’s the only guy). Toomey represented a district which leaned Democrat and won with comfortable margins three times and kept a promise to only serve three terms. He’s very well spoken and a successful businessman. If he is the guy he needs to focus on attacking the bailouts for Wall Street and the pork laden stimulus bills.
