The debate was embarrassing, and I honestly don't see why people are acting like Booker came out looking well. All he did was repeatedly complain about Democrats fighting among themselves. Well no shit, it's a debate. No one is going to distinguish themselves by being overly agreeable with 19 other candidates.
Another thing is they gave way too little time to people like Yang or Gabbard. Harris had a bunch of missed opportunities during the debate, especially in response to Gabbard, and you saw that with her post-debate interviews. It feels like the same "machine" that was behind Clinton is behind her now and I'm a bit dubious about it.
Another puzzling thing is the sheer amount of Democrats all too eager to "cancel" Biden despite him still having the best shot to defeat Trump in key battleground states. It's almost like they like being miserable complaining about Trump 24/7, which considering some of these people I guess it isn't all that surprising.
