Obama has had some of his most famous (infamous?) fugue-like melt-downs in town hall settings (e.g., his "breathalyzer/inhalator" gaffe, and his time when he couldn't formulate a sentence to save his life, even with people shouting encouragement to him).
Not saying he'll have one of those fugues this time around -- but hey, all that cocaine use has to catch up with a person eventually...
