How to Vote in the 2021 St. Louis Mayoral Primary Election

Are you prepared to cast your ballot in the 2021 St. Louis Mayoral Primary Election on March 2? Before you arrive at the polls, there are a few changes to the voting process that you should know.

This year, voters are permitted to vote for as many candidates that they feel are qualified to be mayor listed on their primary ballot. After the March 2 election, votes will be counted, and the top two candidates with the most votes will face off in the General Election on April 6.  

If you would like to cast a vote in this year’s election, the deadline to register is Wednesday, February 3. Absentee ballots can be requested through Wednesday, February 17 at 5 p.m. by visiting this link.

 If you forget to request an absentee ballot but would still like to cast your vote, you can visit the St. Louis Board of Elections Office and vote absentee in person between Thursday, February 18 and Monday, March 1.

Of course, you can also vote in person at your local polling place on March 2. If you do not know the location of your designated polling place, you can use the St. Louis Board of Elections’ search tool here.

Remember, before casting your ballot, make sure that it is marked for the March 2 Mayoral Primary Election before submitting it via mail or in person. For more information on this year’s election, please visit the St. Louis Board of Elections Office website.
