Bernie Sanders could be on the verge of another victory Tuesday, this time in West Virginia, where a poll puts him 4 points ahead of Democratic front-runner Hillary Clinton.

Sanders has the support of 47 percent of Democrats and independents likely to vote in the primary, according to a poll by MetroNews West Virginia.

Clinton is the choice of 44 percent.

The open primary will award 37 delegates and gives the surging Sanders a reason to keep his campaign rolling after his victory in Indiana last Tuesday.

Clinton’s opposition to the coal industry hurts her in the state.
