The Republican Party used to have room for moderates. They were right-of-center, sure, but, they could reason, be reasoned with, and, when appropriate, compromise for the good of the nation.
Not any more.
The Wayward Episcopalian on the Specter party switch. The whole post is worth reading, but this is the clincher:
When I say I’m a fan of balanced government, I assume that both the parties in question are rational, respectable entities. That’s just not the case right now, given the state of the current Republican Party. Go ahead, smash them. Hopefully the phoenix that arises from the ashes would be something with moderates like David Brooks and the moderate Maine duo on its left and respectful conservatives like Chuck Hagel, Lindsay Graham, and Mike Huckabee on its right, with the authoritarian fundamentalist right-wing stuck in a third-party lurch. This is unlikely, but there’s no way I’m going to settle for giving Eric Cantor and Sarah Palin a dominant voice. Until the GOP gets its act together, bring on the Arlen Specters.
