Former presidential candidate Mike Huckabee is a slick, smooth, charming guy. He would've been a dangerous nominee, because he's TV-friendly and quick-witted in a folksy, unthreatening way. But he's actually a rar-right nutcase. And sometimes his jokes fall flat. As in the clip above. If you can't get a laugh from telling a "someone is going to shoot Barack Obama" joke in a talk at the NRA then your delivery needs work, we say. Oh, also we say: wtf.
