Our post debate polling is up!

There are a variety of questions in here, but...

Clearest overall winner: Warren

Mostly good news: Buttigieg, Booker, Yang, Beto, Klobuchar

Mostly bad news: Biden, Castro, Bernie, Harris

Of the top 4 candidates going in, Warren was the only one who emerged with more voters considering her than before the debate. Note: with our polling partner @Ipsos, we re-polled the same voters both before and after the debate, so this data is less noisy than usual.

@Ipsos Warren also got the highest overall grade from voters for her performance, while Castro got the lowest. Relative to their pre-debate favorability ratings, Beto and Booker also qualify as over-performers and Biden and Sanders as under-performers.

@Ipsos Finally, Warren's favorable rating has caught up to Biden's and Sanders's while her *unfavorable* rating remains considerably lower than theirs. This is just one poll so please keep that in mind (we'll have a 2nd wave on Monday). But a pretty robustly good one for Warren so far.
