Conservatives are staying home for this one. That would all but ensure Kamala Harris as the next junior Senator from California.
I wonder if Harris vs. Sanchez could hurt the GOP downballot, particularly in key House races. Many CA Republicans may not have motivation to turn out in a solid D state and a D vs. D Senate race.
Sanchez is going to need to peel off Republicans in the general to win, but she can't be too explicit either or her base could abandon her. And no, her being Hispanic does not mean the Hispanic vote would be locked in for her no matter what. Remember Artur Davis. If Sanchez went too far in trying to appeal to Republicans, Harris could easily run ads about her "trying to get Trump voters" which could backfire on her tremendously. She has a tough needle to thread. She'll probably be better off hoping Republicans begin to see her as the lesser of two evils en masse of their own volition, rather than outright courting them.
