On Tuesday, three pro-impeachment Republicans: Peter Meijer of Michigan and Jaime Herrera Beutler and Dan Newhouse of Washington were on the ballot. Meijer was defeated by a Trump-backed rival, John Gibbs. And, at the time of this writing, Herrera Beutler and Newhouse, appear to be headed to a general election for their races.

The difference? Washington is a state that has an open, non-partisan system that allows the top two finishers in each contest to compete against each other in the general election. This is the model, known as a “jungle primary,” that also facilitated pro-impeachment California Republican David Valadao’s advancement to a general election.

Those three–Herrera Beutler, Newhouse, and Valadao–are the only pro-impeachment Republicans, to date, to survive their primaries…

August 16 will also be an important date for the only pro-impeachment Republican senator on the ballot in 2022: Alaska’s Lisa Murkowski. She has the good fortune of competing in another non-traditional primary, as Alaska holds an open primary and is using a ranked-choice voting system for the first time in 2022. She is widely expected to be competitive. Murkowski is a rarity among pro-impeachment Republicans; her approval rating has risen more than 22 percent since President Joe Biden took office.
