Whether she knew Fuckwit43 was lying egregiously, she will answer for it. Jeb wants to run away from answering for it, that's the difference being pointed out here.You're playing in hypotheticals. I challenge you to find one democrat who will honestly say they did NOT think the vote for the use of force meant the actual use of force. No, they knew going in what it meant, and chose to vote accordingly. Thus, if Jeb is going to be questioned on this, Hillary has a LOT more to answer for (she voted for it, just in case anyone is pretending she didn't).
It's still irrelevant, because Jeb had no authority to either authorize or stop the hostilities. She did. The bottom line remains, though. This won't go very far because it opens the door to Hillary.
