Romney leaving the Senate is not a good thing. He is one of the few rational Republicans left and a major player in bi-partisan legislation getting passed during Biden's first two years. Whoever gets elected in 2024 will likely be much worse than him. Unless that Evan McMullin guy that lost to Mike Lee in 2022 can win the primary.
Applies to really anyone who retired after Trump became President. The extremism is only going to get worse.
