@storyteller your thoughts?
Great list; I like approaching it in tiers. My takes...
1) Warren and Bernie - They were targeted all night by essentially everyone else but they seemed prepared for it. They absolutely owned the Healthcare debate and the "choice" thing didn't seem to take hold with anyone I've spoken to who is less informed or more center leaning (hospitals losing money did however come up a couple of times). Bernie's answer on the border was important in that he folded in support for nations like Honduras and that's a unique but smart take imo. Warren really shined when Tapper and a few others tried to press being open to a first strike with nukes on her. First off, that was a bit disturbing to see and second of all I am supremely impressed that she held her ground and didn't give an inch. They also had the most obvious quotable moments "I wrote the damned bill;" "why would someone get on stage to run for president just to tell us what we can't accomplish;" and "It's not a business" were all really strong.
2) Buttigeig - Pete had two things going for his approach. He was inoffensive to ANYBODY'S constituencies and he managed to play the young card that Swalwell wanted to without making a fool of himself. The neutral thing makes him palatable and I could see him vulturing some of the drop outs support since they'll likely all be groups that support centrist stuff (Bernie and Warren ain't going anywhere). Pete also dropped his one-liner about Dems being called Socialists no matter what they support; I've heard it before but it's effective, accurate and again doesn't offend anyone in the party's sensibilities. He held strong and also left himself a safe choice for an administration position to anybody in the race.
3) Williamson and Beto - Williamson's M4A hesitance is a killer to me because it runs in contrast to everything else she did which was pretty damned strong. Her reparations section is bound to grab attention (although in a roundabout way she kinda admitted she's shortchanging the deal at just 500 billion). Beto meanwhile had a really nice performance compared to last time and got off his ideas well. The problem for Beto is that Pete did it better, so he probably didn't do much for his position. I think they both have a too little, too late set up but they gave themselves a shot to stick around longer.
4) Delaney and Bullock - I don't agree with much of anything they said but they got a TON of questions and attention. Delaney got dunked on profusely but at least he'll be in clips. Bullock avoided getting slammed but also pushed a message that I doubt will take hold with enough people to matter but he drew a clear contrast between himself and others which helps.
5) Klobuchar and Hickenlooper - They tried to do what Delaney and Bullock did but got a lot less time to do it. I actually think they had better answers than Delaney and Bullock but I just doubt anyone will remember them over the top tier performances or the back and forth fights that people like Delaney and Bullock got going.
6) Ryan - I liked Warren's shot at Delaney the best on the night, but Bernie's "I wrote the damn bill" line had a visible hit on Ryan's bug eyed face. It seemed like Ryan came out to fight and get his moment but shrunk when he got clapped on by Bernie. Delaney kept fighting and pushing his agenda, Ryan kinda faded out and got less attention.
Who survives from here? I'd only bet on tiers one and two, though Beto may try to stick it out. Delaney and Hickenlooper's own staffs want them to quit, but Delaney did try to go out swinging so who knows with him. The rest, I don't see what purpose they even have trying to stick around besides trying to negotiate into a cabinet spot. I also think it's worth mentioning that CNN did a trash job and framed everything from a right perspective to the extreme. The immigration questions were framed in a fearmonger style and left no one with a chance to actually be complimentary of the impacts immigrants bring; they pushed first strike with nukes as if Warren's approach is radical; and they gave WAY too much time to some guys with very little attention but who they knew would pick fights. It was embarrassingly obvious that they wanted spectacle and informing the voters fell secondary. We need to cut this debate stage field down. Five people a night, serious competitors only and stop trying to buoy people like Delaney whose own staff wants him out of the race.
