Armstead Jones, board of elections director for Baltimore City, attributed longer lines to the city's lengthy ballot, which piles 20 local questions atop seven state ballot initiatives and the presidential election.

"Of course, if these voters don't take the time to go through the specimen ballot and understand it, we're going to have long lines," Jones said. "If you don't take time to understand it ahead of time, it's going to take 10-15 minutes when you're at the machine."

Jones said he also had to squash rumors that poll workers are turning away voters because a computer glitch said they already had voted.

The long city ballot created a confusing set of choices for Patterson Park residents Mike Brooks and Caitlin Brady, who recently moved from Massachusetts and Pennsylvania, respectively.

"We're not super sure on some of the questions," Brooks said, explaining that he had read through the first three statewide ballot questions. "The rest, do they affect us?"

Scores of children attended the polls with parents in Pikesville, including 9-year-old Benjamin Talesnick, who wanted to head to the polls after seeing John Ogden in a pro-gambling endorsement commercial from Baltimore Mayor Stephanie Rawlings-Blake. Benjamin said he believed expanding gambling would bring more jobs.

"John Ogden really got the kids engaged," said his mother, Robyn Talesnick. "After that commercial, we had been talking about it for weeks."

It took Baltimore lawyer Donna Senft about 50 minutes to vote. Despite the high number of ballot initiatives, people seemed to vote quickly, likely because they had time to read up on the questions in line, Senft said. Others, she said holding up her smartphone, "are doing like me — multi-tasking, going through emails."
