Washington (CNN) - Republican Rep. Cynthia Lummis of Wyoming ripped Liz Cheney's decision to challenge Sen. Mike Enzi for his Senate seat next year in Wyoming as "bad form" and predicted she would lose in the GOP primary next year.
"I don't know that anybody can out-conservative Mike Enzi," Lummis told reporters outside the House chamber on Tuesday. She also compared her to Hillary Clinton when she ran for senator in New York.
The congresswoman, Wyoming's at-large representative, admitted Cheney had the upper hand in raising money, but said that wouldn't matter. "She will outraise him by factors of 10 or more, and he will still win because Wyoming is grassroots, retail campaigning."
Cheney announced her 2014 campaign Monday in a YouTube video, the same day Enzi announced his intent to run for re-election.
Lummis admitted she considered running for the Senate herself if Enzi, the state's senior senator, decided to retire.
"I think she's skipping everyone over," Lummis said.
"In the instance when you have a three term sitting U.S. senator who has does nothing to merit a primary challenge and you challenge that person without the courtesy of calling them just before you make your announcement, it's just not the best way to start a campaign," she added.
On Cheney, Lummis said she's been attending events back in Wyoming, but said "even though she was the shiny new pony at those events, Mike Enzi was there as well talking to people, working hard, being Wyoming's senior U.S. Senator."
Without saying the word "carpet bagger," Lummis leveled the charge that Cheney wasn't really from Wyoming, noting she grew up in Virginia.
"It is a unique strategy to live your entire life elsewhere and then come to a state a year before you're going to announce you're going to run for that state's highest office," she said.
Considering Wyoming's reliably red roots, perhaps Lummis' sharpest slap at Cheney came when she compared her to former Secretary of State Hillary Clinton.
"Hillary Clinton could pull this off in New York. In my opinion, Liz Cheney cannot pull this off in Wyoming and I'm disappointed that she's decided to try," Lummis said. "She should run from Virginia."
