It has lots of good news for SANDERS, BUTTIGIEG and KLOBUCHAR.
It has really bad news for BIDEN.

KLOBUCHAR got the best ratings relative to her pre-debate favorability.
BIDEN and YANG did poorly relative to their pre-debate favorability.
BIDEN's numbers fell quite a lot.
Also not great news for WARREN on this question, and her numbers elsewhere the survey were mixed.
