@Ipsos BIDEN got the highest overall marks for his debate performance, but it's really very close among the top 5. KLOBUCHAR and YANG performed best relative to their pre-debate favorability ratings. BUTTIGIEG and STEYER underperformed relative to their favorability ratings going in. https://t.co/japiRW5uCp — PolitiTweet.org
