He was trying to be tongue n' cheek inferring the Bush won with scare tactics and sliming Kerry (never mind all the untruth's Kerry launched). You probably thought he was for real because he was so off (as libs usually are).

One of the mistakes I forgot to list, that Franken mentioned was that Kerry took too many positions on the Iraq war, the $87 billion, etc. The flip flopping was a legitamate problem.
