Vermont senator Bernie Sanders won the West Virginia Democratic primary keeping alive his long-shot chance of beating front-runner Hillary Clinton in the party's USA presidential race.
Presumptive Republican presidential nominee Donald Trump has cruised to victory in West Virginia.
Votes for his final two opponents, Ted Cruz, and John Kasich, who remained on the ballots in the two states despite dropping out last week, would have been seen as a protest against the New Yorker's status as the presumptive nominee but Mr. Trump won the primaries by big margins.
Mrs. Clinton still holds a significant lead in pledged delegates won in the states, and a massive lead among superdelegates, the party leaders who will likely end up being the deciding factor at the July convention in Philadelphia.
According to exit polls, a third of the state's Democratic primary voters said they identify as independents, and almost seven in 10 of those voters supported Sanders. To secure the Democratic nomination, a candidate needs 2,383 delegates.
A win on Tuesday would bolster his decision to keep fighting for votes through June 7, when almost 700 delegates are at stake, including 475 in California where Sanders is now focusing his efforts. Even if she lost all the rest of the states by a landslide, she could still emerge as the nominee - assuming her superdelegates, the key for her in this race, continue to back her.
Still, Sanders is vowing to fight on. His fundraising has fallen off and so too has his advertising.
Trump himself won easily in West Virginia and Nebraska Tuesday night. He says Trump "thinks 'I can do it on my own, ' but he's wrong". "I think that... now he's been to the Pope, maybe there's another miracle that's going to happen". "I've known about her for 30 years, just like everybody else has".
Ms. Clinton has already largely shifted her focus to the general election and Mr. Trump. Clinton was due to visit a family health center in Louisville to unveil a proposal to increase federal subsidies so that no family pays more than 10 percent of its income for child care.
Clinton's battle with Sanders, who defied pollsters to win in IN last week, has become a source of gloating for Trump.
While trying to make peace with the coal community in Williamson earlier this month, she was met with protests. She is still leading Sanders in terms of delegates and has a 12-point lead over him in national polls.
As in other states, Clinton had the support of the West Virginia's Democratic establishment, but couldn't overcome statements she made in March when she suggested that if elected. she would "put a lot of coal miners and coal companies out of business".
The former NY senator later apologised and said her comments were taken out of context.
While most comments will be posted if they are on-topic and not abusive, moderating decisions are subjective. A few things we won't tolerate: personal attacks, obscenity, vulgarity, profanity (including expletives and letters followed by dashes), commercial promotion, impersonations, incoherence, proselytizing and SHOUTING. But he added: "If circumstances change, we will always assess changed circumstances".
