Their request to break up will be acceptable to me only if they don’t get any more senators.
The division would be as much along political lines as along population and lifestyle lines, so the new senatorial composition would either be 4-4 (good news) or 5-3 (which is the same 2-dem lead that’s the current make-up). So there wouldn’t really be a downside to splitting the state. I’d welcome it to be able to get away from L.A. and the bay area.
