Presidential Preference Primary
March 10, 2020

Since the March 10 election is a partisan primary election, you will be asked to select only one political party's ballot to vote at the time you check in. Missouri conducts "open" primaries, so voters are not registered with a specific party affiliation.


Who is on the ballot?

The certified list of candidates can be found at this link. This list includes candidates from all five of Missouri's established political parties: Republican, Democratic, Libertarian, Green, and Constitution.

While some candidates may have suspended their candidacy, Missouri law requires their names to remain on the ballot, unless they withdrew on or before December 24, 2019.


How do I vote in this election?

In order to vote in the Presidential Preference Primary (or any election in Missouri), you must be registered to vote in the jurisdiction of your residence by the fourth Wednesday prior to Election Day. For the March 10 election, the registration deadline was February 12, 2020.
