Tuesday is the last day you can use the online system to register to vote before the primary election, which is June 26. Early voting is June 14 to June 21.
But if you aren’t registered to vote and don’t make the June 5 deadline, all is not lost.
The Maryland Board of Elections says:
“You can also register to vote during early voting. To make the voting process quicker for you, we encourage you to register to vote by the close of voter registration. If you can’t register by that date, go to an early voting center in the county where you live and bring a document that proves where you live. This document can be your MVA-issued license, ID card, or change of address card, or your paycheck, bank statement, utility bill, or other government document with your name and new address.”
