Robert Frost Middle School in Rockville buzzed with voters and three of the Democrats vying for the party’s nomination for the 6^th Congressional District seat early Tuesday evening.

Candidates and elections judges reported low turnout throughout the day, but by 6 p.m. poll workers said the steady flow of voters was the most they’d seen during the primary.

Between the opening of polls at 7 a.m. and 10 a.m., the precinct reported ballots cast by 90 of the precinct's 1,994 registered Democrats, 44 of 972 registered Republicans and one of 840 voters counted as "other.”

By 3 p.m. the total had increased to 268 Democrats, 148 Republicans and six “other.”

Six voters stood in a swiftly-moving line, waiting in the hallway outside the polling place while four others signed in and six took turns at the voting machines.

“I think this is light because it’s a primary,” said Julian Orenstein, a veteran elections judge.

Polls are open until 8 p.m.
