Massachusetts Attorney General Martha Coakley (D) raised approximately $2 million more for her special election Senate bid over the past month and a half, nearly doubling her total receipts to $4.1 million, the campaign announced Thursday.

Coakley will report cash-on-hand of more than $1.9 million in her pre-primary financial disclosure, covering the period between Oct. 1 and Nov. 18.

Her fundraising edges fellow Democrat Rep. Mike Capuano (Mass.), who announced Wednesday evening that he raised $1.8 million in the period and had $1.1 million cash-on-hand.
