Reporter there are signs of a possible sanders coalition. Last night he won 83 of the youth vote and 73 of independents. But Hillary Clinton still has more minority support, and the states ahead are bigger and more diverse. In iowa and New Hampshire, over 90 of democratic voters were white, but not in nevada with a large latino population. Or in South Carolina where a majority are africanamerican. Do you think its possible for you to win the democratic nomination if you black voters to back you . Well, it is absolutely essential the africanamerican vote and the latino vote, both votes, enormously important. We intend to do very well in both of those communities.

Meanwhile the campaign is already dispatching bill clinton to South Carolina this weekend, a state that has been fraught for him in the past, getting backlash for this attack against barack obama when he ran against Hillary Clinton in 2008. This whole thing is the biggest fairy tale ive ever seen. Reporter clintons hope nevada and South Carolina more diverse and where she now leads are a firewall. A lot will depend on the states top democrat, congressman jim clyburn. Im not ruling out an endorsement before the election. Im just ruling one out for this week.

It could actually be a rerun in this respect, in the way that we thought New Hampshire was going to serve of as the way it would winnow the republican field, help determine who would be the chief challenger to trump and cruz. Now that role goes to south carolinian republicans. Many republican campaigns ive talked to today concede trump and cruz will be one and two and now its the race for third. This time on the democratic side in South Carolina, instead of clinton being the underdog. She plays the favorite and its sanders who playing the game of expectations.
