Four candidates file to run for mayor of St. Louis

The city of St. Louis, Missouri, will hold a nonpartisan top-two primary election for mayor on March 2, 2021. The filing deadline for this election was January 4, 2021. 

Four candidates filed to run for the open seat: 2017 mayoral candidate Andrew Jones, St. Louis Treasurer Tishaura Jones, Aldermen President Lewis Reed, and Alderwoman Cara Spencer.

Candidates of all political affiliations will run in the primary election without partisan labels. Andrew Jones ran as a Republican candidate in 2017 and Tishaura Jones, Reed, and Spencer have previously run for office as Democrats. 

Voters may choose any number of candidates to vote for and the two candidates that receive the most votes will advance to the general election. This method of voting is called approval voting. This is the first election cycle in the city using this primary election method following the approval of Proposition D on November 3, 2020.

Incumbent Mayor Lyda Krewson (D) announced on Nov. 18, 2020, that she would not seek re-election. Krewson became the city’s first female mayor after winning election on April 4, 2017, with more than 67 percent of the vote. 

The last 10 mayors of St. Louis have all been Democrats. The last time a Republican held the mayor’s office was Aloys Kaufmann, who was mayor from 1943 to 1949.

Share of incumbents defeated in contested primaries grows for third even-year cycle in a row

Ballotpedia’s annual state legislative competitiveness study shows that for the third even-year election cycle in a row, the share of incumbents defeated in contested primaries has grown. In the 44 states that held state legislative elections this year, 153 incumbents—61 Democrats and 93 Republicans—were defeated by primary challengers.

Overall, 15.2% of the 1,016 major-party incumbents who faced primary challengers in 2020 lost, the third consecutive increase compared to 2018 (13.8%) and 2016 (12.3%). The loss rate in 2020 also exceeded that of 13.0% in 2014.


  1. 18% of Republicans who faced challenges in 2020 were defeated—the highest since at least 2014.
  2. 12% of Democrats who faced challenges were defeated, lower than the 14% rate in 2018.
  3. More Democrats were defeated in states with Democratic trifectas, as was the case for Republicans in Republican trifectas.
  4. The loss rate for incumbents in states with divided governments exceeds the national average altogether and by party.
  5. Democratic incumbents were defeated at the highest rate in states with Democratic trifectas and at the lowest in those with Republican trifectas. In states with divided governments, the rate exceeded the national average for Democrats.
  6. Republican incumbents facing contested primaries were more likely to be defeated in states with divided governments than in states with trifectas.
