Opinion: Heather Mizeur for U.S. House of Representatives, in Maryland’s 1st Congressional District

U.S. Rep. Andy Harris, the 65-year-old anesthesiologist and former Baltimore County state senator who backs Donald Trump’s fraudulent election claims, once pledged to serve no more than six terms in the U.S. House of Representatives. Given that he is winding up that sixth term in the 1st Congressional District, it’s time to hold him to that long-ago promise. Fortunately, voters have an outstanding choice to replace Harris. Heather R. Mizeur, the Democratic nominee, has campaigned on a trait wholly foreign to her opponent: She has promised to listen, and she has our endorsement.
