SO I’M AT CPAC, helping with the PJTV coverage. The atmosphere here is surprisingly cheerful — people don’t look defeated, but engaged and much happier-seeming than when I was here in 2006 for a book-signing. It was noisy last night, with college-age attendees partying up and down the hall while we tried to sleep. Below is a picture of S.C. Gov. Mark Sanford, telling CPAC attendees that they could learn from the examples of Rosa Parks and Union trooops at Gettysburg.
