2020 United States presidential election in Kansas

The 2020 United States presidential election in Kansas 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. 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. Kansas has six electoral votes in the Electoral College.

Although Trump won the state, Biden's 41.53 percent vote share represented the highest for a Democratic presidential nominee since Barack Obama's performance in 2008 and among the strongest swings to Biden, relative to Hillary Clinton's performance in 2016, in the nation. His 14.65-point defeat represented the first time since 1916, and only the second time ever, that Kansas voted more Democratic than neighboring Missouri, where his margin of defeat was 15.39 points.

Per exit polls by the Associated Press, Trump's strength in Kansas came from white voters, who supported Trump by 59%–38%; white voters with college degrees, however, were tied. This result included a 64% showing for Trump among Protestants and a 74% showing among other Christians. Trump's best margin was 72% in rural areas, while Biden's was 52% in suburban counties.

Canceled Republican primary
On September 7, 2019, the Kansas Republican Party became one of several state GOP parties to cancel their respective primaries and caucuses officially. 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. At its state convention held between January 31 and February 1, 2020, the state party voted to formally bind all 39 of its national pledged delegates to Trump.

Democratic primary
The Kansas Democratic primary was conducted entirely by mail. Votes were counted on May 2, 2020. Joe Biden was declared the winner.

Analysis
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. It was also the first since 1896 that Democrats received a majority in the county. Biden was also the first Democrat ever to win Riley County, anchored by the Fort Riley military installation and Kansas State University; and the first to win Shawnee County, home to the state capital of Topeka, since Bill Clinton's narrow plurality in 1992.

While he failed to break the 56-year Republican winning streak in Sedgwick County, the second most populous in the state and home to the state's largest city Wichita, his 42.9 percent of the vote there was the strongest for a Democrat since Jimmy Carter received 46.5 percent of the vote in 1976. Biden would also build upon Hillary Clinton's share (32.31%) and even break Carter's record at Seward County of 33.96%. At 34.62%, this was the highest percentage of votes a Democratic presidential candidate has won in the county since Lyndon B. Johnson won 46.14% in 1964. 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.
