2020 United States presidential election in Delaware

The 2020 United States presidential election in Delaware was held on Tuesday, November 3, 2020, as part of the 2020 United States presidential election in which all 50 states plus the District of Columbia participated. Delaware voters chose electors to represent them in the Electoral College via a popular vote, pitting the Republican Party's nominee, incumbent President Donald Trump from Florida, and running mate Vice President Mike Pence from Indiana against Democratic Party nominee, former Vice President Joe Biden, and his running mate California Senator Kamala Harris. Delaware has three electoral votes in the Electoral College.

Delaware is the home state of Biden, who represented the state in the U.S. Senate for 36 years from 1973 to 2009. Biden defeated Trump in the state by 19 points, a significant improvement over Hillary Clinton's 11% margin over Trump in 2016, and even a slight improvement over Barack Obama's margin in 2012, when Biden was his running mate. Biden flipped the swing county of Kent, while Sussex County, which last voted Democratic on the Presidential level when Bill Clinton carried it in 1996, stayed Republican, although Biden previously carried the county in six of his seven runs to the Senate. Delaware's remaining county, New Castle—home to Biden's hometown of Wilmington and part of both the Northeast megalopolis and the Philadelphia metropolitan area, containing 55% of the state's population—stayed Democratic, having last voted Republican when George H. W. Bush carried it in 1988, also the last time the state voted for the Republican nominee. Biden's margin in New Castle County would have been more than enough to carry the state; he carried his home county by over 106,000 votes, far exceeding his statewide margin of 96,000 votes.

Per exit polls by the Associated Press, Biden's strength in his home state came from African-Americans with 91%; and Caucasians with 50%, including those with a college degree with 54%. 59% of Delawarean voters had a favorable opinion of him. Biden won overwhelmingly in his hometown of Wilmington, earning 26,698 votes to Trump's 3,580.

With Biden's victory nationwide, he became the first person representing Delaware ever elected president.

Primary elections
The primary elections were originally scheduled for April 28, 2020. On March 24, they were moved to June 2 due to concerns over the COVID-19 pandemic. On May 7, the primary elections were again postponed to July 7. By that time, President Donald Trump of the Republican Party and former Vice President Joe Biden of the Democratic Party had already clinched enough delegates to become the presumptive nominees of their respective parties. This was Biden's third presidential attempt, as he had previously campaigned in the 1988 and 2008 Democratic presidential primaries but failed to secure the nomination both times.

Republican primary
Incumbent President Donald Trump was essentially uncontested in the Republican primary. The state has 16 delegates to the 2020 Republican National Convention.

However, Trump was not unopposed: Rocky De La Fuente took 12% of the vote, with Trump polling 88%.
