Margin of victory: +31.7%

In the 2022 Senate race for MD Senate seat, Chris Van Hollen (D) won with 65.8% of the vote, defeating Chris Chaffee (R) who received 34.1%. 3 additional candidates split the remaining vote. Chris Van Hollen's 31.7-point advantage over the runner-up confirmed a comfortable win.

This was an open-seat race with no incumbent running — Ben Cardin (D) previously held the seat. Open seats typically attract stronger candidates and heavier spending from both parties. As a Democrat, Chris Van Hollen won despite the historical midterm penalty against the president's party (Democrat Biden was in office). The wide margin suggests this district is firmly in the Democrat column for the foreseeable future.
