During the Democratic primary, he was endorsed by state senator Jamie Raskin, various local labor unions and organizations, including the Maryland League of Conservation Voters, CASA de Maryland, and NARAL Pro-Choice Maryland. Moon also ran on a slate alongside Raskin, state delegate Sheila E. Hixson, and William C. Smith Jr. He won the Democratic primary and later won the general election.
