HUNTINGTON, W.Va. (AP) — Republican Don Blankenship doesn't care if his party and his president don't think he can beat Democratic Sen. Joe Manchin this fall.

This former coal mining executive, an ex-convict released from prison less than a year ago, is willing to risk his personal fortune and the Republican Party's golden opportunity in West Virginia for the chance to prove them all wrong.

"I'll get elected on my own merits," Blankenship said this week.

There aren't a lot of things that can sink Republicans' hopes in ruby red West Virginia, where President Donald Trump won by 42 percentage points, but Blankenship could well be one. His candidacy is sending shudders down the spines of Republicans — an already rattled group this election season — who are furiously working to ensure he is not their choice to take on Manchin in November's midterm election.

Blankenship's primary bid is still an outside shot, but the spectacle is testing whether a Republican Party led by an anti-establishment outsider can rein in the party's anti-establishment impulses.

"The establishment, no matter who you define it as, has not been creating jobs in West Virginia," Blankenship said at a primary debate this week.

Even before Blankenship emerged as a legitimate Republican candidate, West Virginia was a worry for some Republicans.

Manchin, a former governor, has held elected office of some sort in West Virginia for the better part of the last three decades. And he's worked hard to cozy up to Trump and nurture a bipartisan brand.

He has voted with the Republican president more than he has opposed him, his office says, noting that the pair have personally collaborated on trade, weakening environmental regulations, gun violence and court nominations.

The alignment with Trump was so effective former White House adviser Steve Bannon worried privately to colleagues that Trump might actually endorse the Democrat. While an outright endorsement now is unlikely, a Blankenship primary victory on May 8 could push Trump to help Manchin — indirectly at least — by ignoring West Virginia this fall.

The state has long been considered a prime pickup opportunity for Republicans, who hold a two-seat Senate majority that suddenly feels less secure given signs of Democratic momentum in states like Nevada, Arizona and Tennessee. If Democrats can win in the state that gave Trump his largest margin of victory in the nation, they may have a slim chance at seizing the Senate majority.

Some of Trump's most prominent conservative supporters, particularly those in Bannon's network, have rallied behind state Attorney General Patrick Morrisey, a fiery, conservative former Capitol Hill aide, who was raised in New Jersey but has served as West Virginia's top lawyer since 2013. Rep. Evan Jenkins, who switched his party affiliation from Democrat to Republican in 2013, has highlighted his West Virginia roots and deep allegiance to Trump.

Jenkins noted that Manchin missed a big opportunity to align himself with Trump on key issues such as taxes and health care.

"The president gave Joe Manchin every opportunity in the early weeks and months of his administration to vote the right way," Jenkins said in an interview. "He voted wrong."

But in interviews this week, both Morrisey and Jenkins declined to attack Blankenship for his role in the 2010 Upper Big Branch mine disaster, the deadliest U.S. mine disaster in four decades. Blankenship led the company that owned the mine and was sentenced to a year in prison for conspiring to break safety laws, a misdemeanor.

Raising that dark history has been left to the national GOP forces believed to be behind the Mountain Families PAC, an organization created late last month that has invested more than $700,000 attacking Blankenship on television. A spokesman for the Senate GOP's most powerful super PAC declined to confirm or deny a connection to the group.

Trump has done his part to hurt Blankenship's chances as well.

The president excluded the former mining executive from a recent West Virginia stop, where he appeared with Jenkins on one side and Morrisey on the other. And Cory Gardner, who leads the Senate GOP's national campaign efforts, had this to say to reporters when asked about Blankenship last week: "Do they let ankle bracelets get out of the house?"

For voters, Blankenship remains a deeply polarizing figure.

Blankenship calls himself a West Virginian but had his supervised release transferred last August to federal officials in Nevada, where he has a six-bedroom home with his fiancee 20 miles from Las Vegas, in Henderson.

"It's a friendly place and I like it," said Blankenship, whose supervised release ends May 9, the day after the primary.

Blankenship recently drew attention for comments on a radio show about the father of Transportation Secretary Elaine Chao, who is married to Senate Majority Leader Mitch McConnell, R-Ky. Blankenship said he believed McConnell has a conflict of interest in foreign relations matters, in particular those dealing with China. Chao's father was born in China and started an international shipping company in New York.

According to media reports, Blankenship's fiancee also was born in China.

"I don't have any problem with Chinese people, Chinese girlfriend, Chinese anything," Blankenship told the radio station. "But I have an issue when the father-in-law is a wealthy Chinaperson and has a lot of connections with some of the brass, if you will, in China."

"He's ruthless, cold-blooded, cold-hearted, self-centered," said Stanley Stewart, a retired miner who was inside the Upper Big Branch mine when it blew up in 2010. "I feel that if anybody voted for Don Blankenship, they may as well stick a knife in their back and twist it, because that's exactly what he'll do," Stewart said in an interview this week.

But there is also skepticism that he was treated fairly by the courts. Blankenship has cast himself as a victim of an overbearing Obama administration, an argument that resonates with many white working-class voters on the ground here.

"What they've said he's actually done (in the criminal case), I don't believe none of that," 21-year-old coal mechanic Zack Ball said while grabbing a bite to eat in the Boone County coal community of Danville this week. "Don Blankenship all the way."

Inside a Whitesville pizza shop a few miles north of the shuttered Upper Big Branch mine, retiree Debbie Pauley said Blankenship "was railroaded" at his trial.

"I think that Blankenship does have integrity," she said. "I don't think he'd put up with any crap."
