[2] Kansas voters chose electors to represent them in the Electoral College via a popular vote, pitting the Republican Party's nominee, incumbent President Donald Trump of Florida, and running mate Vice President Mike Pence of Indiana against Democratic Party nominee, former Vice President Joe Biden of Delaware, and his running mate Senator Kamala Harris of California.

[5] Donald Trump's re-election campaign and GOP officials have cited the fact that Republicans canceled several state primaries when George H. W. Bush and George W. Bush sought a second term in 1992 and 2004, respectively; and Democrats scrapped some of their primaries when Bill Clinton and Barack Obama were seeking reelection in 1996 and 2012, respectively.

Biden's gains relative to Hillary Clinton were powered by significant improvement in Kansas' suburbs and college towns: he became the first Democrat to carry Johnson County, the state's most populous and home to Overland Park and Olathe, since Woodrow Wilson in 1916.

Biden was also the first Democrat ever to win Riley County, anchored by the Fort Riley military installation and Kansas State University;[49] and the first to win Shawnee County, home to the state capital of Topeka, since Bill Clinton's narrow plurality in 1992.

This was also the first election since the three-way contest of 1992 in which a Democratic candidate won at least five counties, along with it being the smallest margin of victory for a Republican nominee since George Bush in 1992.
