GREEN RIVER, Wyoming — The Wyoming congressional primary on Tuesday has been painted as a referendum on Donald Trump. It's a race incumbent Liz Cheney is likely to lose to Harriet Hageman because of her efforts to propel Trump into political oblivion after January 6 and one in which the former president has personally intervened to seek revenge.

But in the sparsely populated state where their ultra-nationalized race is playing out, this primary is just one more battle in a civil war between factions in the only party with any political relevance. Trump is not at the root of the political divide between Republicans here but rather has been an accelerant in a long-running fight between establishment Republicans and a new guard of more doctrinaire conservatives.
