More than one-third of Maryland’s 4.2 million registered have already cast their ballots in advance of the Nov. 5 election, with nearly 1 million cast in early voting that ended Thursday and another 568,359 mail-in ballots returned so far. Those numbers do not include more than 300,000 mail-in ballots that were requested by voters but have not yet been returned, according to the most recent data from the Maryland State Board of Elections.
