Libertarian presidential candidate Gary Johnson and his running mate Bill Weld, the former Massachusetts governor, will barnstorm New England this week, holding campaign rallies in Vermont, New Hampshire, Maine, and, on Saturday, on Boston Common.

The ticket has already qualified for the ballot in Vermont, Maine, and Massachusetts, but still faces an early September deadline to submit petitions to make the New Hampshire ballot.

On Wednesday Johnson and Weld will be in Burlington, Vt.; on Thursday at the New Hampshire State House in Concord; on Friday in Lewiston, Maine; and then Saturday on the Common at the Parkman Bandstand at 1 p.m.
