Romney was breaking the rules in the first segment, too.

He wasn't supposed to "get the last word." He was supposed to go second. Everything after that was up to the moderator. Period.

Jim Lehrer let Romney walk all over him.

Romney lied through his teeth through the whole thing. Let's hope people don't want a pathologically lying arrogant thin-skinned BULLY as their Commander in Chief.

That said; the president should have fought back. Next time he will.
