biden's candidacy, thinking if he fades, they want to pick up his so-called moderate voters. elizabeth warren is fight forge the progressive vote. she wants to come across as a fighter, an extremist and radical and i think she's happy to take the hits. >> that was a shift in this debate. up until now, i think you've seen all the candidates trying to out-progressive bernie and elizabeth. this time they decided the way to do this is pick up joe biden voters and we're going to come back out as the more pragmatic, centrist sort of candidate. paul: you're saying basically because bernie's not going away and he looked hardy, despite his heart attack, looked good, had time in the sun, i think and now he's getting endorsed by alexandria ocasio-cortez. that's a big deal. warren would have loved that endorsement, kyle. >> right, right. but the challenge here is the field is going to get winnoyed.
