Galvin: No one will interfere at the polls, federal or "self-appointed vigilantes"

State of play: Secretary of the Commonwealth William Galvin said he is "concerned, of course, but not terribly worried," about how things will go in Massachusetts.

Galvin said he's fielded a stream of Justice Department letters, which he called "like a pen pal club," but doesn't foresee any federal problems at the polls.

• Federal observers will be in Boston and Lowell, which fall under Voting Rights Act language requirements.
• Observers are a longtime part of the process and are welcome, he said.

Between the lines: Galvin said he is "almost as concerned" about some outside observers who claim to protect voters from interference.

What he's saying: "No one is going to interfere, whether they are from the federal government or private groups or self-appointed vigilantes, whatever they think they are," Galvin said Monday at the State House.

• He added: "They can observe."

The big picture: Galvin said the administration's political attention appears to be focused on states such as Nebraska, Iowa and Alaska — less so on Massachusetts.

What's next: Polls open by 7am and close at 8pm Tuesday.

• State law bars political activity within 150 feet of polling places and requires a police officer at each location.
