In last month's Wyoming primary, Liz Cheney lost in a landslide to Harriet Hageman – the Trump-backed candidate. Cheney was obliterated by a whopping 37.4 points – the second worst defeat for a House incumbent in the last 60 years. Despite the overwhelming lack of support from GOP voters, Cheney is attempting to dictate the direction of the Republican Party.

Cheney appeared at the Texas Tribune Festival on Saturday, where she threatened to leave the Republican Party if former President Donald Trump becomes the GOP's 2024 presidential nominee.

"I'm gonna make sure Donald Trump — I'm gonna do everything I can to make sure he's not the nominee," Cheney told Texas Tribune CEO Evan Smith. "And if he is the nominee, I won't be a Republican."

Smith asked Cheney if she would consider running for president to prevent Trump from a second term, and the congresswoman replied, "I certainly will do whatever it takes to make sure Donald Trump isn't anywhere close to the Oval Office."

Cheney added, "Knowing what I know now, I would not have voted for Donald Trump."

Cheney also pledged to defeat another Republican America First candidate – Arizona gubernatorial candidate Kari Lake.

"I'm going to do everything I can to make sure Kari Lake is not elected," Cheney declared.

"I think we have to do everything we can in '22 to make sure those people don't get elected," she said of Lake and Republican Pennsylvania gubernatorial candidate Doug Mastriano. "We have to make sure Mastriano doesn't win."

Lake fiercely fired back at Cheney for going against her own political party during an appearance on Fox News’ “Sunday Morning Futures.”

"That might be the biggest, best gift I have ever received," Lake jokingly told host Maria Bartiromo. "I mean, the people in Wyoming can't stand her, I'm pretty much sure the people of Arizona don't like Liz Cheney."

"The Republican Party, the new Republican Party, is the party of we, the people," Lake slammed Cheney. "It is no longer the party of warmongers."

"Liz Cheney probably should change her voter registration," Lake quipped. "Turns out she really is a Democrat after all."

On Twitter, Lake mocked Cheney's humiliating defeat, "She's putting more energy into electing Democrats than she did into winning her own primary lol."

Cheney also attacked House Minority Leader Kevin McCarthy, and said he should never become Speaker of the House.

"At every single moment, when our time of testing came and Kevin had to make a decision … he’s made the politically easy-for-him, or the politically expedient, decision instead of what the country needed," Cheney blasted McCarthy.

Last month, Cheney vowed to support opponents of Republican election deniers – even if that means helping Democrats defeat members of her own party.

Cheney – the Republican daughter of former Vice President Dick Cheney – has garnered support from legacy media and Democrats for her anti-Trump stance and being the vice chair of the House committee investigating the Jan. 6 Capitol riot.
