2024 U.S. Senate race in Maryland: Who’s in, who’s out

Maryland’s high-profile race to replace U.S. Sen. Ben Cardin is off to a quick start, with four Democrats almost immediately jumping in for the rare chance to win an open seat in Washington, D.C., next year. Cardin, a three-term senator who’s been involved in Maryland politics for nearly six decades, is not seeking reelection in 2024. Democrats have held both of Maryland’s seats in the chamber since 1987 and are expected to see a competitive and crowded primary race while Republicans are looking to recruit their own candidates.
