Republicans have tried, dozens of times, to repeal the Affordable Care Act, a health-care bill so despised that they termed it “Obamacare.” And dozens of times, despite the clever epithet, they failed. The House’s first attempt in the post-Obama era was canceled only minutes before the vote began; the Senate’s first draft was written in secret; and Mitch McConnell ultimately resorted to a bizarre, and unprecedented, “vote-a-rama” in a last ditch attempt to pass a bill—literally, any bill—as negotiations between moderate Republicans and their more conservative brethren repeatedly collapsed.

Most Republicans in the Senate seem relieved to be moving on to tax reform, the G.O.P.’s Holy Grail since the times of Saint Reagan. But outside the halls of Congress, Republican donors are exasperated. And at least one of them wants his money back.

As The Virginian-Pilot reports, Bob Heghmann, a 70-year-old attorney from Virginia Beach, is suing the G.O.P. for racketeering and fraud, claiming that the party made false claims when it solicited millions of dollars in campaign donations with the promise of repealing and replacing the Affordable Care Act. According to the suit, filed in a U.S. District Court, the Virginia G.O.P. alone raised $20 million from 2009 to 2016, most of it based on the repeal promise.

With the Republican Party apparently unable, or unwilling, to repeal Obamacare—despite holding both houses of Congress and the White House—Heghmann accused the party of “massive fraud perpetrated on Republican voters and contributors as well as some Independents and Democrats.” While Heghmann conceded that individual lawmakers faced difficult political considerations, he claimed that the Republican National Committee, itself, should have done more. “If the candidates don’t deliver, it’s incumbent on the R.N.C. to go to the candidate and say, ‘You can’t do this,’” he said in an interview with the Pilot. Virginia’s two national G.O.P. committee members, Morton Blackwell and Cynthia Dunbar; the Republican Party of Virginia; and state party Chairman John Whitbeck are also named in the suit.

Blackwell and Dunbar told the Pilot that Heghmann’s suit is “frivolous” and “ridiculous,” respectively. Still, Blackwell acknowledged that it was a “sign of conservative anger” over the party failing to repeal President Barack Obama’s signature health-care law. Moderates and hardliners alike have been frustrated by their inability to negotiate a compromise bill, even after seven years of railing against the A.C.A. The last time the Senate attempted to vote on a “skinny” version of repeal—which would have simply lifted the individual mandate, the employer mandate, and various taxes—Senator John McCain ultimately voted the bill down, saying his conscience prevented him from voting for a repeal without a replacement. “We should not make the same mistakes of the past that has led to Obamacare’s collapse,” he said last month, shortly after flashing the thumbs-down sign at a stricken-looking McConnell. Perhaps the Senate majority leader should sue, too.
