What to know about voting on primary day

The primary is May 14.

Polls are open from 7 a.m. until 8 p.m. If you are in line by 8 p.m., you will still be allowed to vote.

You can also register to vote on the day of the primary. You will need to go to an early voting center in the county where you live during early voting or your regular polling place on the day of the primary, and bring a document that proves where you live.

You must be registered with either the Republican or Democratic parties to vote for president, a U.S. Senate seat, or in eight House of Representative races. Some districts, including Montgomery County, will host local races that do not require political affiliation to participate.

You can look up your voting location on the Maryland State Board of Elections website.

What’s on the ballot?

Voters in Maryland will be asked to weigh in on a slew of local races, and there are some extremely competitive contests.


The retirement of longtime Sen. Ben Cardin has touched off a competitive and crowded race to succeed him.

On the Democratic side, a total of 10 candidates are vying for the seat. Prince George’s County Executive Angela Alsobrooks and U.S. Rep. David Trone are seen as the leading contenders.

Trone, the multimillionaire co-owner of Total & Wine who has held his congressional seat in the 6th District since 2019, has poured millions into his Senate campaign.

Alsobrooks, the two-term executive of Prince George’s County — Maryland’s second largest county — has won the endorsement of most major Democratic officeholders in the state, including Gov. Wes Moore, Rep. Steny Hoyer and others.

Alsobrooks would be only the third Black woman elected to the U.S. Senate if she were to win the general election.

One recent poll indicated the race may be tightening amid questions about which candidate is best poised to take on former Republican Gov. Larry Hogan in the fall, and prevent Republicans from winning control of the Senate.

Full list of Democratic candidates

  • Angela Alsobrooks
  • Michael W. Cobb, Sr.
  • Marcellus Crews
  • Brian E. Frydenborg
  • Scottie J. Griffin
  • Robert K. Houton
  • Joseph Perez
  • Steven Henry Seuferer
  • David J. Trone
  • Andrew Jaye Wildman

On the Republican side, there are a total of five candidates, including Hogan, who jolted the race when he announced his candidacy earlier this year. 

Hogan, who left the Maryland governor’s mansion in January 2023 with sky-high popularity ratings, was a popular GOP figure in a state where Democrats outnumber Republicans 2 to 1.

However, he has been criticized by some in his own party for his anti-Trump stance.

Full list of Republican candidates:

  • Moe H. Barakat
  • Chris Chaffee
  • Robin Ficker
  • Lorie R. Friend
  • Larry Hogan
  • John A. Myrick
  • Laban Y. Seyoum

U.S. House

District 6

There are primary contests for all eight U.S. House seats.

One of the most crowded races is in the 6th District. Trone, who was reelected in 2022 by a comfortable margin, is giving up the seat to make his Senate run.

A contentious redistricting process has made it potentially more promising ground for Republicans.

Under the current borders, the district includes all of Allegany, Frederick, Garrett and Washington counties, and a portion of Montgomery County.

On the Democratic side, there are a whopping 16 candidates running, including a number of state lawmakers.

April McClain Delaney, a former U.S. Commerce Department official — whose husband, John Delaney, held the seat before Trone — “is probably the nominal front-runner,” according to Kurtz, with Maryland Matters.

She has been endorsed by Rep. Jamie Raskin, who represents the 8th District.

But she is facing an aggressive challenge by State Del. Joe Vogel, 27, who would be one of the few members of Generation Z elected to Congress were he to win. Vogel also has support from unions and activist groups

Presidential election

The May 14 primary includes both the Democratic and Republican contests. While other names may appear on the ballot — the race for president has narrowed to a two-person contest between Democratic President Joe Biden and former Republican President Donald Trump.

Editor’s note: An earlier version of this story misstated David Trone’s margin of victory over Neil Parrot in 2022. It was not a “razor-thin margin.” Trone won by more than 9.5%.

This report also previously stated that one must be registered with either the Republican or Democratic parties to participate in Maryland’s primary. However, some districts will host local races that do not require political affiliation.

This story has been corrected and updated.
