@Ipsos BUTTIGIEG made the biggest gains in how many voters are considering voting for him. HARRIS and BOOKER also made decent gains by this metric. SANDERS's numbers actually declined a bit; while voters liked how he debated, he may not be persuading new people into his camp. https://t.co/2vGehALmc0 — PolitiTweet.org
