Massachusetts: David Halbert

Doug Bennett, a Republican Boston City Council candidate, said Thursday that he has already knocked on more than 26,000 doors in Boston as part of his amped up grassroots campaign.

Bennett, who lives in the North End, is running for one of the council's four at-large seats. Currently two at-large councilors - Michael Flaherty and Sam Yoon - are rumored to be considering a run for mayor next year, which would create vacancies.
