Lake and Finchem's 210-page petition challenges the use of electronic voting machines, alleging vulnerabilities and lack of proper testing.
Dominion Voting Systems, the manufacturer of the machines, won a significant defamation case against Fox News last year over similar claims.
Despite previous dismissals, Lake and Finchem push for a "do-over" of the 2022 elections, emphasizing concerns over election integrity.
The appeal targets Lake's and Finchem's base but risks alienating general election voters, according to Democratic operatives.
Court observers express skepticism about the case reaching the Supreme Court, citing prior rulings and challenges with establishing standing.
The 9th Circuit Court of Appeals previously dismissed the case, affirming the lack of evidence supporting future election concerns due to voting machines.
Lawyers representing Lake and Finchem face sanctions for filing a baseless case, ordered by U.S. District Court Judge John Tuchi.
