I imagine this also means that Rep. Kevin Cramer has decided not to run. Campbell previously said he was considering the House or Senate seat, and would run for whichever one Cramer wasn't running for. I expect while Cramer hasn't formally announced his intentions, he's likely privately decided to run for reelection instead of senate.
Or it means Campbell is just frustrated with waiting for Cramer, or that he thinks Cramer is vulnerable in a primary (with some of things he's said, it's possible).
