The race in the state's 6th Congressional District was too close to call at the end of Election Day, with 97 percent of precincts reporting and two candidates in a veritable dead heat.
Seven-time Democratic incumbent John Tierney had 48 percent of the vote and Republican challenger Richard Tisei had 47 percent. Third party Libertarian candidate Daniel Fishman received 5 percent of the vote.
Just after midnight, Tisei campaign manager Paul Moore told WGBH that Tisei was concerned about a lack of communication with officials at polling places in Lynn. Moore also said the campaign wanted all military ballots to be counted before a winner was declared.
The race between Tierney and Tisei has been a close one, with the candidates facing off in four debates. The campaign has been characterized by negative advertisements and personal attacks, most notably Tisei's attempt to align Tierney with the gambling scandal in his wife's family.
