To change your party affiliation, use Maryland's Online Voter Registration System (OLVR) or submit a new voter registration application by the close of advanced voter registration, until voter registration opens up again after an election. If you do not select a political party on your voter registration application, you will be "unaffiliated" with any political party. This means that you will generally not be able to vote in party primary elections, but you will be able to vote in any nonpartisan primary elections held in your jurisdiction, such as a primary election to select nominees for the board of education. Register or update voter registration by 4/2/24 (21 days before) to participate in the Presidential Primary Election.
