Mitt Romney was showered in glitter before getting onstage at a rally in Minnesota. The GOP frontrunner laughed about the glitter bombing and his own coif. "Ah, I've got glitter in my hair," he said. "That's not all that's in my hair, I tell you that. I glue it on every day whether I need to or not." The glitter was thrown to highlight Romney's stance against gay marriage, one member of the group explained. Newt Gingrich, Rick Santorum, and Michele Bachmann have all previously been glitter-bombed for similar reasons. Romney wasn't so smooth earlier today when he told CNN he's "not concerned about the very poor."
