6 things to watch in Wyoming and Alaska elections

Jackson, Wyoming (CNN)Former President Donald Trump's campaign to purge the Republican Party of his opponents could reach its most dramatic moment of the 2022 midterm election cycle on Tuesday in Wyoming.

Rep. Liz Cheney, the vice chair of the House committee investigating January 6, 2021, who was booted from her House leadership position and censured by the GOP organization in her state after voting to impeach Trump, faces the Trump-backed Harriet Hageman and three other candidates in the GOP primary for the state's lone House seat.

A Cheney loss would be a demonstration that -- despite the evidence publicly presented by the House committee and the FBI's search of Mar-a-Lago last week in a separate probe -- Republican voters remain loyal to Trump, who's suggested it's a matter of when, not if, he launches a 2024 presidential bid.

Meanwhile, in Alaska, a Trump ally, former Gov. Sarah Palin, is attempting a political comeback. And a Republican who voted to convict Trump in his second impeachment trial, Sen. Lisa Murkowski, faces the first of what's likely to be a two-round showdown with a Republican rival backed by the former President.
