Former governor and 2012 GOP candidate for president Gary Johnson went on the Fox Business Network Thursday night to debate an Obama impersonator, with John Stossel moderating. The weak applause from the studio audience, Stossel’s condescending moderation, the Obama impersonator’s Urkel-esque delivery make this an embarrassing — not to mention un-illuminating — segment. It’s too bad that Johnson wasn’t invited to the CNN debate tonight in New Hampshire, but this is a weak stunt. Call me old-fashioned, but how about just an interview?
