Is this thing on? Mitt Romney attempted to crack a joke about the continuing doubts raised over President Obama’s birth certificate while at a campaign stop in his home state of Michigan Friday. It didn’t exactly go over well—and certainly not with the Obama camp. “I love being home, in this place where Ann and I was raised, where the both of us were born,” Romney said. “No one’s ever asked to see my birth certificate. They know that this is the place where we were born and raised.” An Obama spokesperson tweeted that Romney was “keeping it substantive & classy” with his Donald Trump–inspired line.
