WASHINGTON _ There aren't too many California politicians left on the sidelines in the 2020 primary fight.
Virtually all of California's statewide officials threw their support behind home state Sen. Kamala Harris' Democratic presidential bid shortly after she jumped in the race in January. California's senior Sen. Dianne Feinstein is one of the few backing someone else: former Vice President Joe Biden, a longtime friend and colleague. Speaker Nancy Pelosi has said she will not endorse in the primary.
One high-profile elected official is holding out, however, and he may be the biggest endorsement of all.
