Bernie Sanders Wins 3 Out of 4, Looks for Momentum

The Bernie Sanders campaign is touting its wins in Kansas, Nebraska and Maine this weekend as a sign of life in its quest to overtake Hillary Clinton in the race for the Democratic nomination.

Heading into this weekend's contests -- in Kansas, Louisiana, Nebraska, and Maine -- Sanders faced delegate math that experts say will be hard to overcome. He needed to show some momentum, and he claimed it in the way he has tended, by marveling at his unexpected progress since the start of the campaign.

But Clinton won big in Louisiana and is still acting like the inevitable winner, touting her lead in delegates rather than focusing on the number of states won. (She's won 11, while Sanders has won eight.) Even on Saturday, though, the Associated Press reports Clinton won 57 delegates to Sanders' 52. Then with a sizeable win in Maine for Sanders on Sunday, he was finally able to rack up delegates, adding 15 more to her 7.

The Democrats debated on Sunday night on CNN from Flint, Michigan. The event was moderated by out anchors Anderson Cooper and Don Lemon.
