WRT California 2026, Noisome will be termed out. The prospects of whom I'm aware have problems:
* Kammie lost and made a fool of herself and her supporters;
* Oakland Mayor Sheng Thao got booted from office and indicted for corruption;
* LA Mayor Karen Bass ... besides the incendiary obvious, she has a recall petition in circulation, and the timing of her trip to Ghana proved unfortunate wrt "optics";
* SF Mayor London Breed over-promised and under-delivered wrt cleaning up SF;
* Schifftyroo won't go in for what would probably be a demotion (from Senator);
* Swillwell probably lacks name recognition, and with the Rs in the majority in the House, he probably won't have much opportunity to improve that.
As to the US 2028 Presidential election, the Dem's stable is either glue-factory-ready ancient nags, younger figures lacking name recognition, and younger figures with very negative name recognition (e.g. AOC or the former-SecTrans Pete).
