After citing some examples of the "angry, irrational extremism" we're hearing from the GOP of late ("Obama is a Muslim socialist who wasn't born in the United States", "terror babies", ...), E.J. Dionne asks:

Where are the responsible conservatives who should be denouncing such crackpottery?

...this election isn't even about whether we'll go back into the ditch. It's about whether a movement that's gone over a cliff will be rewarded for doing so. A victory for this style of conservatism will be a defeat for the kind of conservatism the country needs.
