A couple of points that stuck out to me.
For as much crying as Biden supporters have done about his media coverage and a couple of incidents in earlier debates in which other candidates targeted his record, he has not faced anything remotely like the pressure that Elizabeth faced yesterday with 5 or 6 candidates at a time deliberately targeting her and calling her by name with pre-planned criticisms. Given Joe's shaky performances thusfar I can only imagine how ugly it would be were they to gang up on him in this fashion. In rapid fire she was taking criticism from Buttigieg, Klobuchar, Harris, Biden, Gabbard on multiple occasions, and even, I was sorry to see, from Beto. The main source of criticism is just a gotcha game that they are using to score media points by painting her as "evasive" because she doesn't want to give them a sound byte about raising taxes. The fact that a bunch of Democrats are playing this game against universal health insurance when they all realize the cost implications is rather shameful and insincere and yes Amy, you ARE repeating Republican talking points. Painting Democrats as taxers and spenders because they believe government should be run to solve social problems rather line the pockets of rich corporations is a Republican game that goes back at least as far as Reagan in my lifetime.
The second point is that I really think she scored well on the topic of impeachment which is the issue which is consuming the nation. She called for impeachment after reading the Mueller report and to paraphrase... "Look what happened, he was encouraged to break the law again and again since." To me thats a very powerful argument that has been born out by facts and could benefit her in the sort of way that opposing the Iraq War benefited Obama very much in hindsight in 2008.
