Andrew Sullivan rounds up the reactions of the punditocracy. One of my favorites:
[W]hen Perry is asked about the two-hundred and thirty some people he’s executed on death row during his governorship, the audience bursts into applause. Torture, war, and death, and this is the “pro-life” party. I submit to you that this moment is perhaps the most telling since George W. Bush left office; that the modern Republican party is not only intellectually bankrupt, but morally bankrupt as well.
I have a hard time believing that Perry's anti Social Security rhetoric has much future - at least in the general election.
