Throughout Maryland, polling places for voting in the presidential, congressional and county races are open from 7 a.m. until 8 p.m. on Election Day. Anyone in line at 8 p.m. will be allowed to vote.

In Chesapeake Beach, where residents will be voting only for mayor and Town Council, the polls close at 7 p.m. Town residents have to go to a second polling station to vote in other races.

The voter notification card issued to all registered voters should contain the location of your polling place. The information is also available from the county election boards.

* Calvert County Board of Elections, or at 410-535-2214.

* Charles County Board of Elections, or at 301-934-8972.

* St. Mary's County Board of Elections, or at 301-475-7844.

Any voter whose eligibility is challenged will have the right to cast a provisional ballot after filling out an application at the polling place. The provisional ballot will be counted only after the local board of elections has reviewed the provisional ballot application and made a determination that the individual is eligible to vote.

The most common reason that a voter's name is not on the precinct register is that the person moved but did not update his or her voter registration, according to the State Board of Elections. For a provisional ballot to be counted, the voter must be registered in Maryland and must cast the provisional ballot in the precinct where he or she resides.
