Oh, snap!

It sounds like there's been some fashion bitcha$$ness on the GOP campaign trail!

When we were giving former GOP Presidential Candidate Herman Cain a quick pop politics quiz this week, we discovered some very interesting campaign clothing facts.

"I was sporting the sweater vest on the campaign trail long before Rick Santorum tried to make it popular," Herman told us. "But, I'm not upset that he borrowed my idea."

We also got to check out his new tour bus as we learned his post-campaign positions on Sarah Palin, Michele Bachmann, 9-9-9, the iPhone, the BlackBerry and ObamaCare.

We aren't huge sweater vest fans ourselves (being women and all), but we totally dug the politico's new wheels. 

Herman, do you mind if we borrow your tour bus style ... do you?
