History

Historical Context

In August 2018 the DNC voted to exclude superdelegates from the first ballot, and the 2020 Democratic primary opened with a record 29 major candidates, highlighting the party’s centrist-progressive split. Biden’s February 29, 2020 South Carolina victory (48.7% and 39 delegates) propelled him to win 726 delegates on March 3’s Super Tuesday, underscoring senior incumbents’ resource advantage.
