So, Romney had appointed this guy Richard Grenell to be the face of his campaign on foreign policy. Then they started taking flak from the radical right, because Grenell is gay. So they kept him under wraps and wouldn't let him do his job, and after a few days he resigned.
Now, from what I've read, Grenell is a pretty awful person, whose views on foreign policy and national security ought to disqualify him from ever being taken seriously.
But it wasn't Grenell's kooky views on foreign policy that caused the Romney campaign to force him out. It was Romney's cowardly unwillingness to stand up to the religious right. In other words, Romney just signaled that he's willing to sacrifice what he thinks is his best foreign policy expert to appease some loudmouthed Christianist bigots.
Romney as president would be a disaster. The guy has all the backbone of a gummi worm.
