Bernie Sanders and Donald Trump have won their party’s primaries in West Virginia, American media reports.

Exit polls cited by CNN found that Sanders holds an early lead over Hillary Clinton in the West Virginia primary, offering the Vermont Senator a chance to leap back into the political spotlight and confound hardening conventional wisdom that he is an afterthought in the race.

Still, Sanders is mathematically prevented from winning the nomination based on pledged delegates alone, noted CNN.

Meanwhile, Trump was projected to win the West Virginia primary in the first contest since both his competitors – John Kasich and Ted Cruz – dropped out, leaving him as the sole candidate and presumptive Republican nominee.

With these uncontested primaries, Trump moves closer to the 1,237 delegates needed to secure the GOP nomination before this summer’s convention, noted ABC News.

Trump also picked up all 36 delegates available in Nebraska’s Republican presidential primary, which was also held on Tuesday, according to The Associated Press.

The win gives him 89 percent of the delegates needed to win the GOP’s nomination for president.
