Election deniers suffered a stinging series of defeats in Colorado on Tuesday night, losing handily in Republican primaries for governor, U.S. Senate and secretary of state the top three statewide races on the ballot.

Greg Lopez, a former mayor who falsely claimed that former President Donald Trump won the 2020 election, lost his primary to Heidi Ganahl, a University of Colorado regent who finally said in mid-June that she believed President Joe Biden won legitimately.

Businessman Joe ODea, who acknowledged Bidens victory, defeated state Rep. Ron Hanks, a Jan. 6 insurrection attendee, for the GOP Senate nomination.

And in the secretary of state race, Pam Anderson, a former county election clerk who also called Bidens win legitimate, defeated two candidates who questioned the results of the election, including Tina Peters, a county clerk who is under felony indictment on charges that she tampered with voting machines as she tried to prove that the election was stolen from Trump.

Trumps conspiracy theories have dominated Republican Party politics since the 2020 contest, turning this years primaries into a series of referendums on baseless claims of widespread voter fraud, the lie that the election was stolen, and right-wing efforts to take over the countrys election system before the 2024 presidential contest, when Trump may be on the ballot again.

Across the country, GOP candidates have staked their primary campaigns entirely on the big lie. Such candidates have won scores of races nationwide already this year, including Pennsylvanias GOP gubernatorial primary and Nevadas Republican secretary of state race . Michigans state Republican Party backed election deniers for secretary of state and attorney general at its nominating convention. And Republicans who have embraced those lies are leading contenders in major primaries in Arizona, Minnesota, Wisconsin and other states that have yet to hold their contests.

But Colorado is the latest swing state where Republican voters have rejected those conspiracy theories and the candidates who pushed them. In May, Georgia voters similarly turned away a trio of Trump-backed candidates in GOP contests for governor, attorney general and secretary of state, rejecting the big lie in one of its original birthplaces.
