Warren brought in $6.9 million, compared with $3.4 million raised by Brown, according to statements from the campaigns in advance of the April 15 reporting deadline to the Federal Election Commission.
Warren, 62, has raised about $16 million overall for her campaign, compared with $12 million for Brown, 52. He reported $15 million in the bank as of March 30 while Warren had about $11 million, the campaigns said.
Brown, who won a special election in 2010 for the seat that had been occupied by the late Democratic Senator Edward Kennedy, is rated with Dean Heller of Nevada as the two most endangered Senate Republicans in this year’s elections by analysts Charlie Cook and Stuart Rothenberg.
Democrats hold several more seats viewed as vulnerable, and picking up a Republican one could be crucial to maintaining their majority in the chamber. Democrats control the Senate, 53-47.
Warren served as an adviser to President Barack Obama, helping to set the Consumer Financial Protection Bureau that Congress, over near-unanimous Republican opposition, created under the new financial regulation law.
Through Dec. 31, Brown’s biggest source of campaign contributions has been the securities and investment industry, whose employees have given $1.6 million, according to the Center for Responsive Politics, a Washington-based research group that tracks campaign donations.
That’s 13 times the $123,200 Warren raised from that sector. Warren received almost $500,000 from lawyers, and took in $300,000 through Emily’s List, a Washington group that raises money for female Democrats who support abortion rights.
