it was a good night for the republican party overall. great night for most of the democratic candidates up there on that stage. but -- we did learn one really specific, really important thing last night about what will change in washington if we do elect a democratic president to succeed president obama. we learned one really important thing last night that will be really different about his presidency from a democratic presidency that might come next. i'm not sure anybody else has picked up on this yet. it was a quick moment in the debate. i think it is a doozy. and that's next.
