Would be senate pwnag3 for them demz
horserace analysis i've heard for 3 cal posits it as a net positive for pubs. goes from 2 dem senates to 4 dems and 2 swings, but also puts 1/3 of currently dem ca electoral college up for grabs. which, apparently is thought to be a better than even trade.
of course that's 2018, current trending would prolly bring the swing california (socal, btw) back to the dems eventually.
