The outcome of most Maryland primary races has been declared, but election officials still have work to do counting thousands of ballots. They will begin with mail-in ballots on Thursday and follow up with provisional ballots next Wednesday. Key local races, such as Baltimore County executive and Montgomery County executive, are still undecided. Officials expect to finish counting all remaining ballots by July 6.
