St. Louis County saw the highest voter turnout in more than a decade on Election Day 2020, with 78% of registered voters casting ballots on Tuesday, Nov. 3.

In one of the biggest victories, Democrat Cori Bush won the District 1 race for the U.S. House of Representatives with 79% of the vote. She will be the first Black Congresswoman from Missouri.

At the St. Louis County level, Democrat Sam Page was re-elected as County Executive with 58% of the vote.

At the state level:

  • Joe Adams for State Representative in District 86 won after running unopposed.
  • Kevin Windham Jr. for State Representative in District 85 also won, also running unopposed.
  • Republicans will keep a firm majority in both the Missouri State House of Representatives and the Missouri State Senate.
  • Amendment 3 was approved by a narrow margin, with 51% of the vote. It will change the way redistricting happens in Missouri, from the “Clean Missouri Initiative”—a nonpartisan process voters approved overwhelmingly in 2018—back to a bipartisan process with a committee appointed by the governor. The next round of redistricting will happen soon, based on the 2020 Census count.
  • Amendment 1 did not pass. It would have added two-term limits for offices like the governor, secretary of state, and other statewide elected officials.
  • All of the judges on the local ballot were retained on the bench.
