Menino announced Thursday he's ending his 20-year tenure at the end of his current term, opening up what will be a contentious fight and the city's first mayoral race without an incumbent in three decades.
While a handful of candidates are already jockeying for the position, including at least six city councilors and three state lawmakers, according to the Boston Herald, Lynch will continue to pursue the seat vacated by Secretary of State John Kerry (D) earlier this year.
Lynch remains the underdog in his pursuit of the Democratic nomination for Senate against Rep. Edward Markey (D-Mass.), and his name recognition and blue-collar credentials, as well as his Boston background, could have made him a formidable contender in the mayoral race.
But on Thursday, he indicated he'll see the Senate race through to the upcoming primary, on April 30.
