The latest polls show Hillary Clinton has garnered a pretty good lead in Iowa, while Bernie Sanders is again edging ahead in New Hampshire. It possible that the two candidates come out of those first two states roughly equal in delegates. But if that is true, then the third state to vote (South Carolina) seems poised to slam the door in Sanders face.
South Carolina Democrats prefer Clinton over Sanders by a 44 point margin (65% to 21%). This could easily be the state where the dream of "Feel the Bern" begins to die.
The chart shows the results of the Fox News Poll -- done between December 5th and 8th of a random sample of 364 likely South Carolina Democratic voters, with a margin of error of 5 points.
