Factbox-At a glance: March 19 presidential primary states and delegate counts

Five states will hold their presidential nominating contests on Tuesday, a week after both President Joe Biden and former President Donald Trump netted enough delegates to clinch their parties' nomination. Though the two candidates are now looking ahead to their general election rematch in November, Biden is contending with a protest movement from Democratic voters who oppose his backing of Israel's attacks against Hamas in Gaza. The movement, which has had varying degrees of success in states that have already held primaries, is asking voters to mark "uncommitted" on their ballots to register their opposition to Biden's position.
