and webb holding, what can martin o'malley do after riding a summer long hot streak to become the chip leader in new hampshire, is bernie sanders now playing with house money? or will his luck change? and does hillary clinton need to do more than just cover the spread? if she busts tomorrow night, will that be enough to convince vice president joe biden to pony up and join the table? i want to get right to cnn senior political correspondent brianna keilar. brianna, these new cnn/orc polls out this morning from nevada and south carolina seem to suggest that democrats still think clinton is the safe bet. >> yeah, that's right. because they believe, jake, that certainly if you see bernie sanders doing well in new hampshire that after that there may not be a pathway for him to get to the nomination. so hillary clinton they think is still at this point doing significantly better than he is. but at the same time the idea of a loss in new hampshire would be stinging for her. so you'll see her as she is on
