The most painful clip from the Sunday morning shows: top McCain VP prospect Mark Sanford "drawing a blank" (in his own words) on live TV when asked to name a major economic policy that President Bush and John McCain disagree on.
BLITZER: Are there any significant economic differences between what the Bush administration has put forward over these many years as opposed to now what John McCain supports?
SANFORD: Um, yeah. For instance, take, you know, take, for instance, the issue of -- I'm drawing a blank, and I hate it when I do that, particularly on television. Take, for instance the contrast on NAFTA. I mean, I think that the bigger issue is credibility in where one is coming from, are they consistent where they come from.
Sanford finally came up with an answer -- McCain has opposed earmarks while President Bush hasn't -- but Blitzer twisted the knife a bit further, following up on Sanford's initial mention of NAFTA. "He's a huge supporter of free trade, John McCain, the Bush administration supports free trade. I don't see a big difference."
Sanford said he was going to make a separate point about consistency.
