The Democratic Party holds a plurality of registrations in Delaware. Until the 2000 presidential election, the state tended to be a Presidential bellwether, sending its three electoral votes to the winning candidate since 1952. This trend ended in 2000 when Delaware's electoral votes went to Al Gore by 13 percentage points. In 2004, John Kerry won Delaware by eight percentage points. In 2008, Democrat Barack Obama defeated Republican John McCain in Delaware by 25 percentage points. Obama's running mate was Joe Biden, who had represented Delaware in the United States Senate since 1973 and was later inaugurated President of the United States in 2021. Obama carried Delaware by 19 percentage points in 2012. In 2016, Delaware's electoral votes went to Hillary Clinton by 11 percentage points. In 2020, Democratic nominee, former vice president and Delaware resident Joe Biden beat incumbent President Donald Trump in the state by over 19 percentage points. Currently, Democrats hold all positions of authority in Delaware including Senate and House.
