Huckabee's Obama Joke Falls Flat LOUISVILLE, Ky. -- He was known as a presidential candidate with a sense of humor. But Mike Huckabee's joke at the National Rifle Association convention Friday was a dud. Appearing in front of about 6,000 gun rights activists, Huckabee's speech was interrupted by a loud noise. The former Arkansas governor said, "That was Barack Obama. He just tripped off a chair. He's getting ready to speak and somebody aimed a gun at him and he -- he dove for the floor." The comment was immediately noted on news websites and by bloggers who found the crack about Obama getting shot at inappropriate. Obama's campaign had no comment, as it was engaged in a heated back-and-forth with both President Bush and Sen. John McCain -- the presumptive Republican nominee -- over Obama's fitness to be commander in chief. Huckabee provided most of the humor in the 2008 Republican primaries, cracking jokes during several of the debates. He won the Iowa caucuses but failed to reach far beyond the evangelical community in states after that. That wasn't a joke, and it wasn't funny. Sadly it was typical of the insensitive and rude things that have been said by both parties during this election.
