In the 1st District, Rep. Andy Harris, the only Republican member of the Maryland delegation, faces a spirited challenge from a transgender military veteran, Mia Mason, who has gone after Harris for his record on LGBT issues.
The largely rural district covering Maryland’s Eastern Shore heavily favors Republicans.
Partisan gerrymandering has been a particular issue for Maryland congressional districts, and the 6th District had been under legal review.
State Del. Neil C. Parrott (Washington) is trying, however, to return the district to Republican hands.
Here are summaries of all the candidates on the ballot in November:
1st District, Harris vs. Mason
Harris, an anesthesiologist and former state lawmaker, has held his seat since 2011.
He has been a proponent of expanding H-2B visas for the agricultural and seasonal industries at the heart of the economy on Maryland’s Eastern Shore, while also supporting the Trump administration’s strict crackdowns on illegal immigration.
Harris is a longtime opponent of marijuana decriminalization and D.C. statehood who has voted against anti-discrimination measures such as the Equality Act.
His opponent, Mason, says those votes are in part what motivated her to run. She has pledged to support legislation intended to prevent discrimination or disparities in education, the environment and the workplace, among other things.
She also supports federal marijuana legalization.
The candidates differ widely on approaches to the novel coronavirus pandemic, as Harris opposed stay-at-home orders and has been skeptical of the effectiveness of masks, drawing criticism from Mason.
In 2018, Harris easily defeated Democrat Jesse Colvin, although his share of the vote — 60 percent — was lower than his previous three elections.
2nd District, Ruppersberger vs. Salling
In a district that is home to the National Security Agency and U.S. Cyber Command, Ruppersberger has long been focused on national defense and cybersecurity, serving on the House Appropriations Committee and previously as ranking Democrat of the House Intelligence Committee.
He says he has prioritized military readiness abroad and gun violence prevention at home.
Salling, who serves on the state Senate’s budget and tax committee, has described his platform as “pro-business,” supporting cutting taxes and regulations while also pushing for better funding for trade and vocational education.
3rd District, Sarbanes vs. Anthony
Sarbanes, a former state education official, has prioritized election reform, seeking to expand voting rights, end partisan gerrymandering and overhaul the campaign-finance system.
He has also focused on environmental protection, namely to protect the Chesapeake Bay from runoff pollution, while pushing to promote better environmental education in public schools.
Anthony has said he supports ensuring health care is affordable and lowering taxes as a way to create jobs, but he has provided few details.
