FILE - In this Tuesday, June 5, 2018, file photo, "I Voted" stickers wait for voters at a polling station inside the library at Robert F. Kennedy Elementary School in Los Angeles. Californians start voting Monday, Feb. 3, 2020, in a high-profile Democratic presidential primary that has no clear front-runner. The March 3 primary was moved up from its usual June date so Californians might have more of a say in the outcome of the primary and the decision about the eventual Democratic nominee.
