Bush brain fart
Actually, Bush made *exactly* the same mistake -- saying Osama where he meant Saddam (or vice versa) -- in one of the debates last fall.
The slip was noted, but he sure wasn't "cruified" for it in the post-debate media coverage, nor do I recall many people suggesting he wasn't qualified for the job, that the GOP had screwed up in nominating him, or that his butt should should be rocketed to Antarctica.
