Trump will say anything to get attention.
He knows the suckers are listening.
Cui bono?
Bingo!
FWIW, Sometimes silence is NOT golden. Like it or not, there are many concerns (not just birth certificate) many of us have that the neutered RINOs are content to accept and not question or discuss (like Rove, Romney, Huckabee, et al). THAT is a problem! For all anyone knows, Trump may not even run for president, but he IS asking questions and many of us are appreciative he is doing so.
You can rudely call inquisitive people "suckers," or you can attempt to comprehend we, the people, are thankful there is someone willing to ask questions that no one else is willing to ask on our behalf.
