Many of Paul's supporters were ordinary folks who have never participated in the political process before. A lot of them, when they heard about Paul, went to their local GOP offices to help out only to be sneered at or turned away.
It's unfortunate that Paul did not denounce the moonbats, racists, and anti-war activists that were exploiting his campaign, but at best these people represented a miniscule fraction of his real support.
Most supporters are racist, truthers, dope heads and wackjobs....But that's OK, as long as they proclaim the banner of liberty. And in so doing elect Obama.
