Maryland voters set matchups for Open House seats


The Democratic nominees for three open House seats in Maryland include a county executive, a senator and a former Biden administration official, the latter of whom faces a potentially competitive race in November.

Here is an overview of the races:

2nd arrondissement

Baltimore County Executive John “Johnny O” Olszewski won the Democratic nomination to replace retiring Rep. CA Dutch Ruppersberger.

Olszewski had 82 percent of the vote in a six-way primary when The Associated Press called the race at 8:41 p.m.

Olszewski will face Kimberly Klacik, a conservative radio host, in November. Klacik won a three-way Republican primary and had 65 percent of the vote when the AP called the race at 8:43 p.m. Klacik previously ran in the 2020 special election in the 7th District to replace the late Rep. Elijah E. Cummings.

Olszewski, who previously served in the House of Representatives for nearly nine years and was considered a potential Senate candidate before choosing to endorse Angela Alsobrooks, is the favorite for the seat. Democrat Joe Biden would have won the district by 20 points in 2020, and Inside Elections with Nathan L. Gonzales rates the race as Solid Democratic.

3rd District

Sen. Sarah Elfreth won the nomination Tuesday to replace retiring Rep. John Sarbanes, defeating nearly two dozen fellow Democrats, including former Capitol Police Officer Harry Dunn, who drew national attention to the race.

Elfreth had 36 percent of the vote when the AP called the race at 10:27 p.m. Dunn trailed by 26 percent.

Dunn gained a national following after speaking about his experiences defending the Capitol on January 6, 2021, including in a best-selling book. That helped him raise $4.6 million as of April 24, far more than anyone else in the field, including Elfreth, who raised $1.5 million.

But outside groups placed ads on Elfreth’s behalf, closing the gap in the airwaves. United Democracy Project, the independent expenditure arm of the American Israel Public Affairs Council, spent $4.2 million to boost Elfreth, the youngest woman ever elected to the Senate. A group called Pro-Choice Majority 2024 dropped $175,000 in radio ads supporting Elfreth ahead of the final weekend of the campaign, according to Federal Election Commission filings. She touted the endorsements of retiring Senator Benjamin L. Cardin and former Senator Barbara A. Mikulski.

Elfreth is the favorite in November. The 3rd District would have supported Biden by 25 percentage points in 2020, according to Inside Elections with Nathan L. Gonzales, which rates the race as Solid Democratic.

6th arrondissement

The contest for what will likely be Maryland’s most competitive House race this year comes after voters from both parties picked their nominees on Tuesday.

Democrat April McClain Delaney, a former Commerce Department official, won the Democratic nomination, leading a crowded 16-candidate ballot, although some of those candidates dropped out before the election. McClain Delaney had 40 percent of the vote when the AP called the race at 10:21 p.m. Del. Joe Vogel came in second with 26 percent.

McClain Delaney, whose husband, John Delaney, previously represented the district, was endorsed by former Speaker Nancy Pelosi and by Maryland Rep. Steny H. Hoyer, Jamie Raskin and Ruppersberger.

If elected, she would succeed Rep. David Trone, who gave up the seat to run for Senate. Trone had succeeded her husband when he ran for president in 2020.

McClain Delaney will face Republican Neil Parrott, the 2020 and 2022 GOP nominee in the district. Parrott, a former member of the House of Representatives, had 50 percent of the vote in the seven-candidate field when the AP called the race at 10:02 p.m.

Dan Cox, another former state lawmaker who lost the 2022 governor’s race, had 29 percent.

Inside Elections rates the race as likely Democratic.
