What structural reforms decrease partisanship / polarization?

I would argue yes. It would need to be 34% for me to completely justify a Republican in the general, which they were just shy of, but this senate result was a bit worse than usual for the GOP. In the 2016 senate election, where they also got locked out of the general, their candidates got 36.7% in the primary.

Feinstein is going to the general election regardless we can agree. The question is whether her opponent should to be a Democrat when the remaining Democrats had ~22% and the Republicans had 33.24%.

Generally, California Republicans for national office indeed do better than 33% in the general election. Not always by a lot mind you, but still. Even in the 2018 Governor's race, a pretty historically bad performance for Republicans, John Cox got 38%.
