The polling reinforces another piece of data the Club for Growth released a year ago, which showed that 52 percent of Wyoming GOP primary voters were planning to vote against Cheney regardless of who challenges her.

Yet this week provided evidence that GOP primary voters were willing to come back to some Republicans Trump branded as enemies, as Georgia’s Gov. Brian Kemp, Secretary of State Brad Raffensperger and Attorney General Chris Carr all won primaries against Trump-backed challengers.

And Cheney has remained undaunted by the forces assembling against her. In a video released Thursday, timed to coincide with her filing for reelection, Cheney touted her Wyoming roots, said she refused to “surrender to pressure or intimidation” and cast her upcoming election in grave terms.

“If our generation does not stand for truth, the rule of law and our Constitution, if we set aside our founding principles for the politics of the moment, the miracle of our constitutional republic will slip away,” she said. “We must not let that happen.”
