voters want to connect with their presidential candidates. and warren just gave them a really good reason to do that. >> what's your read on why buttigieg seems to be overtakinging her in the polls? >> i think that buttigieg is certainly doing a lot of work, he's gotten a ton of press and a ton of attention. and people are trying a lot of things out. i will say this. i worked for john edwards in 2004. we were a surprise second. the surprise first in iowa there was john kerry, who at this point in the race was polling sixth in iowa. we've got a lot of ground to make up here. >> axios is reporting on this news of this 2020 chaos theory, with democrats saying a very realistic scenario could be pete buttigieg winning iowa, warren taking new hampshire, biden winning south carolina, bernie sanders winning nevada. how do you see this going down to convention or no. or is that the worst-case scenario. >> i think we'll see what happens. i think we have so much time left and momentum matters. but obviously, we have time left. we still have candidates getting in the race.
