10. According to the Cook Report, Sanders needed to win 70% of the Iowa delegates to be competitive

According to one of the experts for the Cook Report, Sanders needs to win big in Iowa to have a chance http://talkingpointsmemo.com/dc/sanders-needs-more-than-a-win-in-iowa-to-beat-clinton

As David Wasserman wrote in the Cook Political Report last week, "98 percent of pledged Democratic delegates will come from states with lower shares of liberal whites than Iowa and New Hampshire." That is a big problem for Sanders who has yet to prove he can expand his base....

Yet, even then, delegate allocation is proportional, which means that Sanders would have to begin winning by major margins to make the race a serious contest.

Wasserman estimates that according to his models, Sanders would "need to win 70 percent of Iowa's delegates and 63 percent of New Hampshire's delegates" to even "be on track" to stay competitive with Clinton in later states where demographically speaking, Clinton has shown she has more support. And in a states like Florida and South Carolina, Clinton leads in recent polls by 36 points and 19 points, respectively.

"It is not merely the delegate process that favors Hillary, it is the voters. She has earned the loyalty and support of communities of color, women, the LGBTQ community, environmentalists, and other vital parts of the Democratic coalition," says Democratic strategist Paul Begala, a Clinton supporter. "Bernie's coalition - so far - is more narrow. It is impressive in its energy and its passion, but it is, I think, more narrow."

The Cook Report has some good analysis
