Voter turnout in Maryland is expected to be heavier than normal, because the nominations for president haven't yet been determined.

Adding to voter interest, a high-profile U.S. Senate race is being decided Tuesday. There are also two strongly contested U.S. House primaries.

In the Senate race, Reps. Chris Van Hollen and Donna Edwards have been battling in a contentious Democratic primary, as Sen. Barbara Mikulski retires at the end of her term.

The race for Senate has opened up two congressional seats in districts that include the suburbs of the nation's capital.

Baltimore voters are deciding a crowded Democratic mayoral primary that includes state Sen. Catherine Pugh and former Mayor Sheila Dixon as front runners.

A record-high number of Marylanders cast early ballots during the eight-day, early-voting period that ended Thursday.
