First Lady Michelle Obama and Dr. Jill Biden were in Florida today for a NASCAR event, and they didn't exactly receive a warm welcome. They were supporting Joining Forces, a White House initiative to hire and train veterans, which is about as unobjectionable as they come. The ladies received a standing ovation at a pre-race event, but then when the two of them were introduced to the crowd at the race there was a loud, sustained booing sound. (You can hear it starting at the 1:36 mark below.) So much for good sportsmanlike conduct, NASCAR fans!
