I think the biggest takeaway from this debate is a confirmation that Trump is not some infallable God that cannot dodges every hit in a debate, but rather that no one had taken any serious shots up to this point.
I think it comes too late in the primaries to matter but it bodes well for the future where Hilary faces off against Trump 1 on 1.
Also I guran-damn-tee he drops a slur before the election.
Romney would have eviscerated him in the primary. Why it's taken up until now for someone to do it is beyond me, but the *one* thing his team was good at was taking other candidates out of the fight with an orbital bombardment of assaults.
Trump is really thin skinned, not very good at pivoting, and has baggage the likes of which make Newt Gingrich look like a saint. It's a mark of how appallingly incompetent and lazy the republican's have been to let it get to this stage.
