Voters went to the polls in Alabama, Alaska, Arkansas, California, Colorado, Iowa, Maine, Massachusetts, Minnesota, North Carolina, Oklahoma, Tennessee, Texas, Utah, Vermont, and Virginia.

Biden won easily in all 16 states that had caucuses or primaries. Trump won 14 of 15, with former South Carolina Governor and former U.N. Ambassador Nikki Haley winning in Vermont. (The Iowa caucuses on Tuesday were only for Democratic voters; the Republican caucuses in that state took place on January 15.) Haley, the last serious challenger to Trump's dominance of the Republican Party, had earlier won the Washington, D.C., primary. She dropped out of the race a day after Super Tuesday but did not endorse Trump.

Voters in many states have yet to vote, but Biden and Trump have all but clinched their respective party's nominations. Biden is expected to be nominated at the Democratic National Convention, which takes place in Milwaukee August 19–22. Trump looks to be the one nominated at the Republican National Convention, July 15–18, also in Milwaukee.

Current pledged delegate totals are 722 for Trump, who needs 1,215 to clinch the nomination, and 1,497 for Biden, who needs 1,968.

The date of the general election is November 5.
