Last year, when Rubio was asked if he thought President Obama’s birth certificate was fake when speaking in front of a Tea Party crowd, Rubio replied, “I don’t know the answer to that.”
Easy. The media say's the birth certificate is legit, so it is legit. To back it up, Hawaii's dept. of health gave Obama a paper that says "this isn't his birth certificate, but we say he was born here, and our proof is, well, we say he was born here."
