It’s almost too silly to mention, except that the suggestion seems to be getting some traction on YouTube and the blogs .
I’m gonna say no. If you look at the full video , you can see the audience was already pretty jazzed at that point, and Obama had just delivered the line that Clinton was “in her element” during Wednesday’s debate. The “mischievous smile” doesn’t come until his “twist the knife” line, and at that point hardly seems like a throwback to the questionable scratch. Plus, think about it: Flipping your opponent off, however subtly, is pretty freaking unwise. He may be young and inexperienced, but he’s not politically suicidal.
What we need is a video montage of how Obama scratches his face. Is the one-finger an anomaly or his standard scratching method? This is why God invented crowd-sourcing.
Update 3:08 p.m.: Alternate angles cast yet more doubt on the finger theory.
