Mitt Romney goes birther: 'No one has ever asked to see my birth certificate'

Mitt Romney in Commerce, Michigan just a few minutes ago:

Now, I love being home in this place where Ann and I were raised, where both of us were born. Ann was born in Henry Ford Hospital, I was born in Harper Hospital. No one has ever asked to see my birth certificate. They know that this is the place that we were born and raised.

The crowd, predictably, went nuts.

9:48 AM PT: Actually, Boston Globe columnist Joan Vennochi has asked to see Mitt Romney's birth certificate. She wanted to know if his middle name was really Mitt'or whether it was actually Milton. But here's what Mitt really doesn't want to be asked to produce: his end user software license.

9:50 AM PT: I guess this is what Mitt was thinking of when he asked the president to "take your campaign of division and anger and hate back to Chicago."

9:52 AM PT: Obama camp: "Romney's decision to directly enlist himself in the birther movement should give pause to any rational voter across America."
