David Vitter faces down a pre-screened mob

Manly, diapered rethug Sen Vitter isn't worried about disruptions at HIS town hall meetings.

Vitter seemed to mock his colleagues, saying that although he had been advised to have "security" for his town hall meetings, he "told them the best security is to do what the people want you to do." He added that "the angry mob is always welcome at my events."

As long as the mob is angry at the other guy. Plus, it doesn’t hurt when all of the questions to you are pre-screened and the audience is selected in advance.
