@Ipsos In terms of net favorability, WARREN saw her numbers improve, though not by as much as KLOBUCHAR, BUTTIGIEG or STEYER. However, SANDERS saw his net favorability get worse, as did BIDEN. Thus, Warren started the night behind Sanders in net favorability and ended it ahead of him. https://t.co/UMg31ZKPyb — PolitiTweet.org
