A new era in DC politics is on the horizon as voters head to the polls for the city’s June 16 primary election, with early voting taking place June 8–14. Voters will choose candidates for mayor and, for the first time in more than three decades, select a new delegate to the U.S. House of Representatives.

Mayor Muriel Bowser is not seeking a fourth term, and Del. Eleanor Holmes Norton is stepping down after 36 years in Congress. Eight candidates are competing for the Democratic nomination for mayor, along with one Statehood Green Party candidate. DC Councilmembers Janeese Lewis George and Kenyan McDuffie are considered the frontrunners.

This election will also mark the District’s first use of ranked-choice voting. Under the new system, voters may rank up to five candidates in order of preference. First-choice votes are counted first. If no candidate receives a majority, the candidate with the fewest votes is eliminated, and those ballots are redistributed to voters’ next-ranked choices. The process continues until one candidate earns a majority and is declared the winner.

In addition to the mayoral race, the ballot will include contests for attorney general and several DC Council seats.
