* Andrew Yang: If I told you even three months ago that there would be a time in mid-October in which there was an extended conversation in a Democratic debate about the dangers of automation, you would have laughed at me. And yet, there we were on Tuesday night — a full debate within the debate, about Yang’s pet issue. It’s a testament to Yang’s remarkable rise in this race — second only to Buttigieg’s — and to the fact that he is already having a significant impact on the conversation within the Democratic Party. Plus, that “MATH” pin was straight fire.
* Amy Klobuchar: At the moment, the Minnesota senator hasn’t qualified for the next debate in November. Knowing that, Tuesday night was her last best chance to make a real move. And to her immense credit, she went for it. Knowing that Warren is now the front-runner (more on that below), Klobuchar went right after her. “Your idea is not the only idea,” Klobuchar told Warren at one point. At another, she tried to make clear that Warren had no monopoly on “bold” ideas. At yet another, she accused Warren of “making Republican talking points right now.” I’m not sure it changes anything in her polling. But she deserves credit for taking her best shot(s).
* Kamala Harris: Nothing Harris did on Tuesday night will change her trajectory — downward in this race. Her “Dude gotta go” line about Trump fell flat, as if the audience had sort of been there and done that. Harris’ attempt to force Warren to agree with her that Donald Trump’s Twitter account should be suspended felt small and not terribly effective. Harris has simply not been able to recapture the magic she had in that first debate of this election; Tuesday night was another swing and miss.
* Tom Steyer: When the most interesting thing about you in the debate is that you wore a plaid Christmas tie, you didn’t have a good debate.
