That was in the case of a retirement. This is a death and reappointment. I am unsure if the new Senator would assume Sen Feinstein's previous committee assignments, but all of my instincts around the Senate say no. So we are back in the position of relying on the GOP to allow the new Senator to fully serve and represent the 39 million citizens of California. If you know anything about the modern GOP and their despise for democracy, you know they will never let that happen.
Sorry, California, the 39 million of you only get 1.3 senators for the next 15 months. The 576 thousand people of Wyoming will still get their full 2.
