LAS VEGAS (AP) — A Nevada judge declined Friday to order a new election in Clark County and Las Vegas for a Republican congressional candidate who lost by nearly 5% to an incumbent Democrat.

Clark County District Court Judge Gloria Sturman pointed to a 33,000-vote margin that Jim Marchant would have to make up to overtake U.S. Rep. Steven Horsford in the state’s most populous and Democratic-leaning county, and said she lacked jurisdiction to order do-overs in six other counties in what she called the “geographically enormous” congressional district.

“How is it fair to just revote in Clark County?” she asked.

Marchant and his attorney, Craig Mueller, didn’t immediately respond to messages about whether they will appeal.

The same judge is due on Monday to hear a similar request by Mueller for a revote on behalf of Dan Rodimer, a Republican candidate who lost his bid for Congress by nearly 3% to Democratic U.S. Rep. Susie Lee in a district wholly including Clark County.

In both cases, Mueller alleges misconduct by election officials, an inability to track mailed ballots and that the use of an optical scanning machine to validate voter signatures was improper.

Attorneys for Clark County and the state and national Democratic parties said similar arguments were rejected by state and federal judges.

“These issues have been aired and litigated extensively,” said Kevin Hamilton, an attorney representing the Democrats. “This is not a close election.”

Mueller lost his bid for access to computer voting records from the Clark County Registrar of Voters, and to present evidence he said he has that ballots were cast on behalf of unqualified, inactive or dead voters and that ballot signatures didn’t match.

Sturman also was scheduled on Friday to take up a bid by a conservative former Nevada lawmaker and her voting watchdog group to block statewide certification of the Nov. 3 election results.

Claims of voter fraud by Sharron Angle and her Election Integrity Project of Nevada are not as broad as those made in an election challenge that President Donald Trump's campaign attorneys filed Tuesday in the names of six would-be GOP presidential electors.

It seeks to nullify the election or have a state judge declare Trump the winner.

Campaign attorneys claim the Republican president won Nevada despite results showing he lost to Democratic President-elect Joe Biden in Nevada by more than 33,000 votes.

The judge and hearing date in that case changed late Thursday. It is now scheduled for a hearing Dec. 1 in Carson City.
