This is why he is not ready to be President. He, along with other would-be candidates, needs to learn to think before he speaks, and not spout off-the-wall stuff, even if he does believe it, unless he’s ready to die on that particular hill.
If we want an adult as President, you're right.
But Dems say loopy, stupid, off-the-cuff stuff ALL THE TIME and their accomplices in the media NEVER call them on it. During his first campaign (and even his second) Obama tried to look so smart that he came off looking like an idiot ("57 States," "Do you know the cost of Arugula?," "Bitter clingers," "You didn't build that," "If I had a son," etc., ad infinitum).
And he's at the top! They ALL say nutty, offensive stuff!
If Ben had the sort of "air cover" the average donkey has, it would have been spun away at worst.
