Wow, tonight may have changed the race, both the debate and the Squad (minus Pressely) endorsement of Sanders.
1. Warren is far better at taking fire than Biden is, and actually had a good debate, wiping the floor in the second half, wiping out Harris (she may very well be out of the race) and more importantly, Biden. She must address this stupid rhetorical game the center likes to play though on middle class taxes for Medicare For All. She must do more than just not take the bait. Still the frontrunner and pundits tend to underestimate how well her debate performances are received.
2. Buttigieg may now be the centrist to beat, not Biden, though Buttigieg is to the left of him. Buttigieg had his best debate, but his rise could ensure a Warren victory by leeching from Biden. Biden simply put, is a terrible debater and a terrible candidate. He was terrible handling the question about his son, and at the end, decided not only is it a good idea to take on BOTH Sanders and Warren at once, but to be completely rude to Warren in which Warren laid him out.
3. Sanders is not out of the race, not only because of a good debate performance, but because...
4. AOC (and Omar and Tlaib) endorsed Bernie. This may actually be the first real mistake I think she has made. I can see no benefit to her in this (unless of course he steals the nomination). At worst, she can cause Sanders to surge but not enough, splitting progressives between Sanders and Warren, and allowing Biden to win (If Buttigieg doesn't leech his support). Other than Barack Obama, she is the only endorsement that can have a real impact. She needs to understand her power and it would have been better if she waited until the primaries, because her power can impact the race. Had her endorsement come month's earlier, it could have knocked Warren out of the race. However, its also possible that her endorsements only stop Sanders from losing more voters to Warren, as most of her supporters already support Sanders, but would not prevent a warren victory. A bright spot is that she is friends with Warren, so her clout will not be harmed if Warren wins, and would be an asset to Warren as well. This endorsement will consequences we can't foresee, but its not a good move on AOC's (or Omar and Tlaib's) part.
