What you need to know about the 7th District special election Tuesday

Tuesday is officially the special election for Maryland's 7th Congressional District, but thousands of voters have already sent in their ballots for who should succeed the late Rep. Elijah Cummings. Amid the coronavirus, the state asked everyone in the 7th District to vote by mail, if they could. There will be three in-person voting centers open Tuesday, but officials encourage only people who can't vote by mail to use them.
