WAKEFIELD — On a sweltering Friday evening, Edward J. Markey walked briskly through a half-empty playground, extending a hand to a few parents as they watched their children romp. “Can I say hello? I’m Congressman Markey. Can I say hello?” he said. He spent only a few seconds with each and did not pause to reminisce with a young mother who said she knew Markey and was from Malden, his hometown.
“Great,” he said, without delving into their shared connection. “So I’d ask for your help,” he said, and moved on. “The election is in 25 days.”
