Those weird Motocross ads must be working. 

GOP presidential candidate Jon Huntsman yesterday picked up what must be a coveted endorsement among bike riders: The approval of Annapolis native (and extreme biking king) Travis Pastrana.

Pastrana is the only human being on earth who can do a double backflip on a bike, and he's usually not political. But he decided to ride into the political mud for his friend and fellow rider Huntsman. 

Here's how @travispastrana endorsed @jonhuntsman on Twitter:  

"Not one 4 politics, but @JonHuntsman, fellow MX rider, good friend of @NitroCircus &smartest man I know, is running 4 President. Look him up." 

Up until now, I thought Huntsman was, like Pawlenty, too boring to capture the Republican nomination. But if Pastrana likes him, how bad could he be?
