The House committee investigating the attack on the U.S. Capitol will hold its first public hearing on Thursday with Rep. Liz Cheney in attendance.

According to polls and interviews with state Republicans, Cheney's undoing with GOP voters in Wyoming is due to her national platform and crusades.

According to a survey by Wyoming Values, Cheney is behind Hageman in the GOP primary by a wide margin. The survey was conducted by Tony Fabrizio. Republican Insiders say it tracks other polls in the state.

Bill Cubin said the race is getting baked in against Cheney. It wouldn't be so much that she's participating in the Jan. 6 Committee, but there's this feeling she's not really representing Wyoming anymore

Some Cheney supporters privately echo the same sentiment, but her campaign categorically denies that she has no way to come back before the primary.

The executive director of the Wyoming Mining Association said she has been friends with the industry for a long time.

She and her staff are accessible and responsive. She has served the industry well.

Last week, Cheney released her first major statewide ad buy that tacitly spoke to the challenge by featuring testimonials from everyday Wyomingites lauding her candidacy and her home state.

The race is a measure of how little Republican voters care about the Capitol riot, and it is also a test of the power of Trump's endorsement. One of the most important things to Trump is that Cheney became the most outspoken House Republican to call him out and impeach him for inciting the mob.

The Wyoming Values poll was released a day before the first public hearing of the Committee.

Hageman was leading by 8 points when she first entered the race. Now she's ahead by 28 points after the ad buy promoted Trump's endorsement of Hageman and framed Cheney as a tool of Pelosi.

One of the three Republicans in the race ran an ad that bashed Cheney for voting to impeach Trump. The Club for Growth ran a commercial that compared her to Clinton.

According to a memo obtained by NBC News, there is no room for Cheney to get back into the race. A huge majority of people say they will vote against her even if she doesn't like Cheney. She has hit her ceiling because only 26% of people say they will definitely or probably vote for Cheney.

The survey did not directly measure attitudes about the Capitol riot, nor did a survey that was conducted by the Club for Growth.

Cheney's opposition to Trump and her role on the Jan. 6 committee are too damaging to her candidacy in Wyoming's Republican primary.

She is on the wrong side of things.
