Republicans in Nebraska and West Virginia head to the polls today.
Donald Trump is the sole candidate still campaigning in the GOP race, following decisions by rivals Ted Cruz and John Kasich to suspend their campaigns.
Still, Trump continues working to solidify support with some in the party. House Speaker Paul Ryan has declined to endorse the presumptive nominee, so far. And Nebraska’s own Sen. Ben Sasse published an open letter on Facebook criticizing Trump.
Cruz added fuel to the anti-Trump sentiment on Tuesday, suggesting that a come-from-behind win in Nebraska could alter his decision to drop his own bid.
"We launched this campaign intending to win. The reason we suspended our campaign was that, with the Indiana loss, I felt there was no path to victory," he said in a radio interview, according to The Hill. "If that changes, we will certainly respond accordingly."
Ahead, catch up on the results from contests held so far. And be sure to check back to see how things continue to unfold. Results for the Democratic primaries can be found here .
