Apparently, "taking on the establishment" is GOP code for "I wanna keep my job"

Firebrand GOP Rep. Madison Cawthorn takes on 'establishment' with district switch

Rep. Madison Cawthorn, a conservative Republican firebrand, shook up next year's congressional race on Thursday night when he announced he would run for a different congressional district -- effectively pushing a more traditional state lawmaker who was expected to run out of the race.

"North Carolinians don't settle for the status quo. We defy it. We made history together last year when you sent me to Washington to shake up the swamp and fight for you," Cawthorn said in a video he tweeted on Thursday.

"I have every confidence in the world that regardless of where I run, the 14th Congressional District will send a patriotic fighter of D.C. But knowing the political realities of the 13th District, I'm afraid that another establishment, 'go along to get along Republican' would prevail there. I will not let that happen. I will be running for Congress in the 13th Congressional District."

Cawthorn is a thoroughgoing trumpkin, supporting and imitating his idol, even emulating his cravenness.
