next up, bernie sanders on the run, wants the black vote. and later, bernie goldberg, ed henry. we're coming right back. >>> impact segment tonight, bern, baby bern. >> what the people here have said is that given the price, it's just too late for the same old, same old establishment politics and economics. the people want real change. >> joining us now from chicago is dr. austin brewsbi. >> i don't think people paid enough attention to the advantage trump gets. the only real question is are his people going to vote? they showed tonight they are. there is a huge advantage when it starts coming to super tuesdays in which we have a series of them, 6, 8, 10 primaries on the same day for someone who already has national name recognition. he doesn't have to build the ground game. other guys are going to try to struggle to get their name on the front page and build out field offices and he starts with an advantage there. but you can't get the nomination with 34%. and if guys like kasich can stay and win his own state, or someone like rubio or bush can stay in and win their own states
