Yesterday, David Brooks and I had a very lively and productive debate about what has gone wrong with conservatism in America and how to fix it. The event was sponsored by the CATO Institute. We agreed on some; and disagreed vehemently on some. We also responded to some provocative questions and challenges from the packed crowd. David homed in one some of the weak spots in my book and I did my best to respond. I think it was a debate that actually fostered more light than heat. Imagine that.
