So far, I'm disgusted with John Delaney for his incredibly rude behavior. Not at all impressed with Tim Ryan because he made mistakes on readily known facts. Inslee was so bland that he might as well not be there.
Impressed to different degrees by Klobuchar, O'Rourke, Gabbard, Warren, Castro, Booker, and De Blasio's command of the facts, their ideas, their passion, and how they've conducted themselves to define and share their platforms.
Each of them had their moments to shine.
I think that Beto O'Rourke and Warren stood out from the others, likely increasing their supporters the most.
