"I'm drawing a blank" -- Response from Possible McCain Veep pick when asked to name economic policy differences between Bush and McCain

This is destined to be a classic in the annals of blowing one's chances to be V.P. -- not that it's really Mark Sanford's fault. It was really a trick question. There are no differences between Bush and McCain.

From Nico, who has the transcript and the video:

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.

The transcript:

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.
