Even if he wins, you can bet that he'll limp into the chamber and meekly support strong border enforcement. Yeah I know he voted for HR 4437 but c'mon you and I both know his butt would have been barbecued even more by conservatives during the state convention.
Unfortunately, the lesson people will get from all of this is that the border enforcement crowd is lead by a bunch weirdos. It is a real shame and for whatever victories one might get with a single House vote, the success of the movement depends on popular support.
