Wolf's campaign will send drivers into the city today to help voters get to the polls, Turchinetz said. Galluccio said he will do the same, running shuttles from Huron Towers and other locations.

The 27th District seat was formerly occupied by Massachusetts House Speaker Charles F. Flaherty, who stepped down last spring after being convicted of income tax evasion and state ethics abuses.

Before Flaherty, the seat was held by U.S. House Speaker Thomas F. "Tip" O'Neil.

This is the first election in Cambridge tallied by the city's new electronic polling system, meaning results will be available sometime tonight. Results previously were not available for several days, as election workers counted the ballots by hand.
