Hillary Clinton and Bernie Sanders go head-to-head in West Virginia today.
The state’s political environment looks to favor Sanders, who trails the former secretary of state in the overall delegate count heading into the final weeks of the primary. And it's yet to be seen whether Clinton's earlier comments on coal will hurt her when voters go to the polls. The website FiveThirtyEight predicts that Sanders will win by between 3 and 7 percentage points.
Still, closing that pledged delegate gap will be near impossible for Sanders given the remaining contests.
Democrats will also vote in a primary in Nebraska, but, as CNN notes, the election there doesn’t impact delegate counts.
We'll be updating here with the expected winners as it becomes clear. Ahead, catch up on the results from contests held so far. And be sure to check back to see which candidate emerges the winner of the day.
