Super Tuesday

It was a surprise result for the former vice president, who won a majority of states on Super Tuesday. He rode a wave of momentum that may have catapulted him back into front-runner status.

Super Tuesday is the biggest day of the Democratic primary campaign. Fourteen states will hold nominating contests to pick who they think should square off this fall against President Trump.

On Super Tuesday, 14 states including California, Colorado and Utah will all cast ballots. The western states increasingly rely on mail-in ballots that often take longer to count. More than 60% of California voters cast absentee ballots in 2018 and it took weeks to call some races in California and Arizona that year.
