Katie Couric's one-on-one with Sarah Palin -- Jonathan Martin at The Politico thinks it didn't go well: "Not only did Palin say the country could be facing another Great Depression without a bailout, but she offered a painful silence when pressed about campaign manager's Rick Davis's ties to Freddie Mac.  And, at the end, she had no good answer when asked by Couric for examples of what McCain has done to regulate Wall Street."
