State Treasurer Steven Grossman accelerated his gubernatorial campaign fund-raising in the second half of September, after Attorney General Martha Coakley launched her own bid, giving him a commanding lead in the money race for the 2014 Democratic nomination.
Grossman raised $141,985 in the final two weeks of last month, bringing his September haul to $164,770 and his campaign kitty to $729,325, according to state campaign finance disclosures.
Coakley, who announced her candidacy on Sept. 16, collected about $28,000 in the second half of last month, bringing her account to about $258,000, a campaign adviser said, adding that Coakley had not begun holding fund-raising events.
After Grossman, the Democrat with the most lucrative September was former homeland security official and Globe op-ed columnist Juliette Kayyem, who netted $88,318, the bulk of it after Coakley’s announcement, and had $202,528 on hand.
Biotech executive Joe Avellone claimed $63,61, with $121,495 in his war chest.
Former Medicare and Medicaid chief Donald Berwick banked $53,215, giving him a $264,650 balance.
The five candidates are seeking the right to represent the Democratic party in the November 2014 election to succeed Governor Deval Patrick. The primary election will be held next September.
