I think there is room in the party for some moderates. Norm Coleman is an example of a good moderate. He was strong on pro-life issues and the war, supeprb on the UN OIl for Food investigation, but was more with the democrats on green issues. HOWEVER, he wasn't a spy or a saboteur. He made it plain from the outset that he would be voting as his constituents in Minnesota wished on global warming issues. That's ok with me, because he said it up front, allowing the party to make arrangements to accommodate his vote.
Specter, on the other hand, keeps people guessing, and even when it is shown that he is not backed by his constituents, and even when he has been proven wrong, he still votes against the GOP.
But the absolute worst thing, to me, is that he has been working actively with the democrats for some time, and was no doubt reporting what happened in GOP caucus meetings to the democrats. That is dishonorable and there is no excusing it.
Norm Coleman lost to both Jesse Ventura and Al Franken, if that doesn’t spell “Loser” I don’t know what does.
