Mr. Moore, 68, said he was worried that several of the other candidates were too old to be president, and that was one of the reasons he chose Mr. Steyer, 62, a former hedge fund manager. “He just seems to have an energy about him that comes across,” Mr. Moore said.
Also leaving the polling site were Mark and Gina Marriner, a married couple who said they had wanted to vote for Mr. Steyer but chose former Vice President Joseph R. Biden Jr. in the end.
“We didn’t think Steyer had a chance in the long run,” said Ms. Marriner, an antique art dealer. “We preferred Steyer but felt that Biden was the best chance to beat Trump.”
Mr. Marriner, a retired employee of the state health and environmental agency who was drawn to Mr. Steyer’s environmental record, suggested that the businessman turned environmental activist would be good as head of the Environmental Protection Agency.
About a mile away at a Masonic Temple, voters in Ward 9 were also sleeping in, according to Benjamin Tyler, the captain.
“It’s going to be kind of slow,” Mr. Tyler said. “A lot of people are voting absentee.”
Mr. Tyler, a retired firefighter who runs a landscaping company, said he became a poll captain after first working as a poll watcher.
“I fell in love with the process,” Mr. Tyler said. “I wanted to be a part of something in the community.”
