A man who believes the Holocaust did not happen and whose own party calls him a “Nazi” has won a GOP primary in Illinois for a seat in the United States House of Representatives.

Arthur Jones — whose campaign website includes a flier that calls the Holocaust the “biggest, blackest, lie in history” — ran unopposed in the state’s 3rd District on Tuesday and claimed the victory after previously running (and losing) five times before. Even though he ran without an opponent, more than 20,000 voters cast their ballots for Jones.

Republicans aren’t exactly celebrating. The GOP nominee is so reviled that his own party has denounced him. In the past weeks, Illinois Republicans have put forth a calling campaign that implores voters to “stop Illinois Nazis.”

“Arthur Jones is not a real Republican — he is a Nazi whose disgusting, bigoted views have no place in our nation’s discourse,” Tim Schneider, the Illinois Republican Party chairman, said in a statement to the New York Times. Schneider also vowed to put up “real campaign dollars” to oppose Jones with an independent candidate.

Even the National Republican Congressional Committee, which is spearheading the effort to keep the GOP’s tenuous control of the House, has refused to endorse Jones.

Jones has little chance of succeeding. He’s running in a solidly blue district including part of Chicago and its suburbs that has been held by Rep. Dan Lipinski, a Democrat, for years. He’ll vie for the House seat in the 2018 midterms against the Democratic nominee.
