Trading the slavery of NorCal from Los Angeles County to the new masters of San Diego and Orange Counties? No.
Admittedly, slightly better flag idea than the State of Jefferson, but with the demographic shifts of Orange & San Diego counties, it'd be two more solid blue senators in a very short time.
At least this map makes sense grouping counties together that actually have commonality with each other. Yes, I do dislike leaving most of the southern reaches of the central valley out of it, but realistically, a more compact region makes the most sense.
It'd have it's own challenges, especially with Roseville, Redding and Chico, but I think we can handle it.
