Via Sullivan, David Frum thinks of Arlen Specter's defection pretty much what I do—except he's not as happy about it:
Pat Toomey is of course the former president of the Club for Growth who planned to challenge Arlen Specter in the 2010 Pennsylvania Republican primary. Polls showed Toomey well ahead – not because he is so hugely popular in the state, but because the Pennsylvania GOP has shriveled to a small, ideologically intense core. Toomey now looks likely to gain the nomination he has sought – and then to be crushed by Specter or some other Democrat next November.
...I submit it is better for conservatives to have 60% sway within a majority party than to have 100% control of a minority party. And until and unless there is an honored place made in the Republican party for people who think like Arlen Specter, we will remain a minority party.
By the way, I'd rather have an actual opposition party than what we have now. But this sort of thing has to happen about once in a generation. And 40 years from now, after the U.S. has swung farther left than most Americans can tolerate, it'll be our turn again.
Parker's emergency bath, by the way, was successful. He is now allowed back in the house.
