Rubio lacks integrity. I really don't care about his position on guns at this point. He has SOME good fiscal ideas. But he's unelectable to anything but what he's got right now, and that's tenuous. He's the political equivalent to the Peter Principal.
Don't see how they can continue to call it a red herring in any reasonable sense since the durkas have been turning trucks and vans into pedestrian battering rams all over Europe, but okay.
