I remember that Romney and Santorum were down by 6-8 about 3 days ago.
Either a HUGE Super Tuesday BOUNCE for both of them, or WHACKO SCOTTY TROLLING.
I believe it's the latter.
So, in effect, something like, an 11-point swing from Obama (-5) to Romney (+6) and an 8-point swing from Obama (-4) to Santorum (+4) over the past four days, while the president's approval has slipped (49-50) -1 to -10 (44-54)
Rather puzzling, given that nothing has happened for the worse that should have caused such a movement
