Today is the biggest day in the Democratic presidential race with 14 state primaries, including the large California and Texas primaries, and the American Samoa caucuses taking place.
Follow our liveblog for coverage throughout the day:
There are now four candidates left in the race: Bernie Sanders, Joe Biden, Mike Bloomberg and Elizabeth Warren.
Biden and Sanders are expected to do well in key states while Bloomberg is officially entering the race today. Warren's campaign has flagged in the latest contests so a poor showing today could spell the end of her run.
By the end of the day, we could have a clear picture of who the next nominee is, or it could signal the Democrats are headed to a brokered convention where superdelegates decide the race.
