on this measure. liz both warren is also doing better better. >> what about when you compare biden and sanders? why is that? how could it be that bernie sanders is the best liked democrat even though he's trailing? because voters have a favorable view of both of them. 52% have a favorable view of both of them. among those who have a favorable view of both, joe biden is beating sanders by 20 points. it's not just about being liked. it's about being loved. and the voters who like both biden and sanders really love biden and are going with him. >> that's interesting. >> yeah. you know, another thing i'll sort of point out here. we're talking about the favorable ratings. this is among all registered voters. let's broaden it out. this to me is a troubling trend for democrats. all of the democrats here, not a single one of them has a net positive favorability rating.
