Former U.S. Senate candidate Juan Dominguez, a Severna Park business executive, has joined a large field of candidates — including five state lawmakers and a former U.S. Capitol Police officer — vying for the 3rd Congressional District seat being left open by the retirement of Democratic Rep. John Sarbanes. Dominguez, 56, a Democrat and Gulf War veteran whose parents emigrated from Cuba, had previously announced for the U.S. Senate seat now held by Democratic Sen. Ben Cardin, who is not seeking reelection.
