Presumptive Democratic nominee Joe Biden on Tuesday chose California Sen. Kamala Harris as his running mate, which would mean an open seat if she becomes vice president.

California's Democratic Gov. Gavin Newsom would choose someone to fill the seat until Harris' term runs out in 2022. Should Biden lose, Harris would remain as a senator and likely run for reelection.

Here are some potential Democratic candidates that Newsom may choose for the seat.
