Voters in Alaska and Wyoming head to the polls today for primary elections. In Wyoming, pro-Trump primary challenger Harriet Hageman is poised to unseat incumbent Congressmember Liz Cheney amid backlash over Cheney’s role as one of two Republicans on the House January 6 committee.

In Alaska, former governor and 2008 Republican vice-presidential nominee Sarah Palin leads a crowded field seeking to fill Alaska’s lone U.S. House seat, which had been held by Don Young for nearly a half-century before his death in March.

Meanwhile, Alaska Senator Lisa Murkowski faces 18 Republican primary challengers, including pro-Trump candidate Kelly Tshibaka. Last year, Murkowski was one of just seven Republican senators who voted to convict then-President Trump after the House impeached him over the January 6 Capitol insurrection.
