AP Decision Notes: What to expect in Maryland's state primary

Maryland voters head to the polls Tuesday for a primary that will determine statewide nominees, settle two closely watched congressional races and keep the fight over redistricting in view as ballots are counted.

The election is set for Tuesday, June 23, 2026, with polls scheduled to close at 8 p.m. ET. Because Maryland is heavily Democratic, many of the most important contests will be decided in the party primaries rather than in November.

Gov. Wes Moore and Lt. Gov. Aruna Miller are seeking the Democratic nomination for a second term. Moore enters the race as the best-known figure on the ballot, but he still faces Democratic challengers Eric Felber and LaTrece Hawkins Lytes.

On the Republican side, the gubernatorial primary is crowded, with nine candidates vying for the nomination, including former Del. Dan Cox. The size of the field makes the outcome harder to predict and underscores how much of Tuesday's attention remains on the Democratic contests.

Statewide contest

Moore's renomination bid is the marquee statewide race. He and Miller are running as the incumbent ticket, and the primary will show whether Moore can cruise through or whether any protest vote emerges in the Democratic electorate.

The race also carries a broader political profile because Moore is one of the most prominent Democrats in the state and has been discussed nationally as a rising figure in the party. Even so, the immediate question on Tuesday is simply whether he secures a second-term nomination without drama.

Maryland has about 4.6 million registered voters, and Democrats hold a majority of them. That gives the party's primaries unusual weight in determining who will represent large swaths of the state in Washington and Annapolis.

A crowded House ballot

The busiest congressional contest is in Maryland's 5th District, where 24 Democrats are competing to replace retiring Rep. Steny Hoyer. The open seat has turned the race into a wide-open scramble in one of the state's most politically important districts.

Among the better-known contenders are Harry Dunn and Quincy Bareebe, whom the AP preview identified as leading fundraisers in the field. In a race this crowded, fundraising and name recognition may matter as much as ideology, especially if the vote splits across several candidates.

The 5th District is also notable because its winner will emerge from one of the state's most competitive and high-profile primary fields. The eventual nominee will inherit not just the seat but a district with national attention because of Hoyer's long tenure.

In the 6th District, Rep. April McClain Delaney faces former Rep. David Trone in a Democratic primary that has drawn outsized notice. Trone launched his comeback bid after losing his Senate race, setting up a rematch-style contest for the seat he previously held.

That race is one of Tuesday's most closely watched because both candidates are well known and because the outcome could help define the state's next House delegation. The AP preview says the contest is among the key races to watch as results come in after polls close.

Redistricting backdrop

Another reason the primary matters is that Maryland lawmakers are still considering redistricting that could affect the state's only Republican House seat in future elections. The issue has not produced a final map fight yet, but it remains active enough to shape the political conversation around the primary.

Earlier efforts to push redistricting stalled, but the debate has not disappeared. A commission-backed proposal this year has kept the possibility alive, and the AP preview notes that a future redraw could put Maryland's lone Republican House district at risk.

That gives Tuesday's vote significance beyond the immediate nominating contests. The outcome could influence how quickly redistricting returns to the legislative agenda after the primary, and whether lawmakers move on the issue again once the campaign pressure eases.

What happens next

The first returns are expected to come from early and mail-in ballots, followed by election-night results after polls close at 8 p.m. ET. In a year with a crowded 5th District field and a closely watched 6th District race, the order in which ballots are counted will matter.

The key unknowns are straightforward: whether Moore wins renomination comfortably, which candidates emerge from the 5th District's crowded field, how close the Delaney-Trone race becomes and whether redistricting quickly returns as a legislative issue.

For now, Maryland's primary is a test of both the state's Democratic hierarchy and the political map that could still change after the votes are counted.
