Liz Cheney thought she would end Harriet Hageman's political career in 2022.
Even then, she didn’t fully know how dead wrong she was.
And Harriet Hageman just made one move that has Donald Trump grinning from ear to ear.
Trump's Giant-Slayer Eyes the Senate
U.S. Senator Cynthia Lummis shocked Wyoming conservatives last Friday when she announced she wouldn't seek reelection after just one term.
Republicans worried another GOP seat could be in play.
But Congresswoman Harriet Hageman just ended that panic with one announcement that sent shockwaves through Washington, D.C.
Hageman declared her candidacy for the U.S. Senate on Tuesday, and just like that, Wyoming's seat stays in America First hands for decades to come.
The 63-year-old Congresswoman who crushed Liz Cheney by 37 points in 2022 wasted no time jumping into the race.
"We must keep up this fight, and that's why today I'm announcing my campaign for United States Senate," Hageman said in her campaign launch video.¹
Trump's fingerprints are all over this announcement.
Hageman made clear the President is "well aware" she's running and that she'd "welcome his endorsement" a third time.²
Trump backed Hageman in both her 2022 and 2024 House races when she became one of his most reliable conservative warriors in Congress.
Now she's ready to take that fight to the Senate where RINOs and Democrat obstructionists need a reality check.
The Woman Who Destroyed a Political Dynasty
Hageman's political rise is pure poetic justice.
In August 2022, she obliterated then-three term incumbent Liz Cheney in what became the second-worst defeat for a House incumbent in 60 years.
Cheney scored 68.6% of the vote when she won reelection in 2020.
Two years later after she voted to impeach Trump and served on the sham January 6th Committee, Hageman beat her by nearly 40 points – 66.3% to 28.9%.³
Cheney's defeat marked one of Trump's biggest scalps in his mission to purge disloyal Republicans who stabbed conservatives in the back.
Trump endorsed Hageman in September 2021 after Cheney decided attacking Trump mattered more than representing Wyoming's 70% Trump-supporting voters.
Over 100 Republican House members followed Trump's lead and backed Hageman.
Cheney outspent Hageman by more than 3-to-1 – raising over $15 million compared to Hageman's $4.5 million – and it didn't matter one bit.
Wyoming voters weren't buying what the Never-Trump establishment was selling.
The daughter of former Vice President Dick Cheney became radioactive in Wyoming after she prioritized her obsession with Trump over the interests of her constituents.
Hageman reminded voters that Cheney "betrayed Wyoming, betrayed the country and she betrayed me."⁴
Wyoming Republicans heard that message loud and clear.
Trump's Senate Reinforcement
Hageman brings exactly what Trump needs in the Senate – proven loyalty, legal firepower, and a spine of steel.
As a water and property rights attorney who spent 34 years fighting federal overreach, Hageman knows how to take on the administrative state.
She serves on the House Judiciary and Natural Resources committees where she proved to be a thorn in the side of the Biden bureaucrats trying to crush American energy production.
Hageman chairs the Subcommittee on Water, Wildlife, and Fisheries and also serves on the Subcommittee on Energy and Mineral Resources.
She's exactly the kind of conservative fighter Trump needs to advance his America First agenda while establishment Republicans like Mitch McConnell head for the exits.
"President Trump's America First movement made it popular to say you want to Make America Great Again, and he continues to deliver on that promise," Hageman said in her announcement. "It would be a great honor to keep advancing the America First agenda in the Senate, as it has been in the House."⁵
Lummis praised Hageman as someone who can "hit the ground running" – and she's right.⁶
With Trump winning Wyoming by 46 points in 2024 and Hageman crushing her 2024 reelection opponent by 48 points, whoever wins the Republican primary essentially wins the seat.
The Club for Growth PAC immediately endorsed Hageman, recognizing she's been a champion of "free-market policies" who has "opposed spending increases" and "championed deregulatory efforts."⁷
Wyoming Superintendent of Public Instruction Megan Degenfelder endorsed Hageman less than 30 minutes after her announcement, calling her "the fighter that we need to defend the conservative movement in this country and in Wyoming."⁸
Secretary of State Chuck Gray quickly followed with his endorsement, praising how Hageman has "advanced our Wyoming values" and protected "Wyoming industries and our way of life."⁹
Why Democrats Are Panicking
Here's what keeps Chuck Schumer up at night about Hageman moving to the Senate.
She's not some establishment Republican who talks tough during campaigns then folds the second Chuck Schumer looks at them sideways.
Hageman spent decades in the courtroom battling federal agencies and environmental extremists who wanted to destroy Wyoming's energy economy.
She knows every trick in the Washington, D.C. playbook – and she's not intimidated by any of it.
When Trump needs 51 votes to confirm his Cabinet picks or pass America First legislation, Hageman delivers.
When Senate Republicans need someone to expose Deep State corruption, Hageman leads the charge.
And when Democrats try their usual obstruction stunts, Hageman fights back with the same intensity she brought to ending Liz Cheney's career.
Trump knows exactly what he's getting with Harriet Hageman – a proven winner who kept her promises, defended his policies when RINOs like Liz Cheney were running scared, and has the conservative credentials to deliver for Wyoming and America.
Liz Cheney tried to bury Harriet Hageman's political future.
Instead, Hageman buried Cheney's career and is now positioned to become one of Trump's most important Senate allies for the next generation.
