Alaska Sen. Lisa Murkowski has occasionally voted against her Republican Party, making her one of the more moderate members of what’s become a party full of right-wing extremists. She opposed Brett Kavanaugh‘s Supreme Court confirmation, voted to protect the Affordable Care Act at a precarious time, and voted to convict Donald Trump after his second impeachment.

It’s that last one that’s most upsetting to the MAGA cultists and as a result, Murkowski will have challengers in her primary when she runs for re-election next year. One of them is Kelly Tshibaka, an Alaska state official, who announced this week she was resigning from her job as the state’s Commissioner for the Department of Administration in order to focus on her upcoming race. She has already enlisted the help of a number of Donald Trump campaign operatives.
