HRC couldn't pass an FBI background check. She couldn't pass a simple background check for a security clearance. Therefore she is not qualified to be the commander-in-chief of the US military. She can't even be present in the room when the joint chiefs of staff brief on-going and future operations. She'd have to get the dumbed down, sanitized version of what's going on.
It says a lot about Obama, imo. But then again, he's the guy who saw fit to release 100+ terrorist prisoners back into service for terrorist groups like ISIS. So poor judgment goes hand in hand with the position, in his view.
