My take on night 2:
Good:
Harris, clearly the winner, wove her story and policies together. The pic of her as a young girl has gone viral. Knocked Biden off his pins. A lot of people left hoping to see her use her prosecutorial skills against Trump.
Swalwell, some good answers, especially on gun control, won't get nomination but possibly seek open Senate seat from California
Buttigieg, acknowledged without glossing over or excusing problems between police and Black community, willing to say he needs to work on a problem, refreshing after current occupant of White House who praises himself for everything and blames everyone else.
Bad:
Biden, started well, parried Swalwell's comment about passing the torch, but fell apart when Harris got going. Saying desegregation should be left to local authorities was exactly the segregationist position, no one from the government should tell us in Mississippi how to treat "our n-----s". If Harris got under his skin, what would Trump do?
Sanders, nothing wrong with showing passion but he is permanently stuck on 11. I don't like being constantly yelled at. When candidates were asked about one signature issue he went into a rant about political revolution no one understood.
Yang, chance to introduce himself, underwhelmed, others who proposed national income put an income limit on it but he did not. Should Bill Gates get $12,000 a year in taxpayer money?
Williamson, trying to sell books
Hickenlooper, a good governor but had to say "I am not a socialist" every sentence
Gillebrand, I agree on campaign finance reform but it is not the answer to every question
Bennet, did he say anything?
