“Thanks largely to your help, we just capped off our largest fund-raising quarter since the special election in January 2010,’’ Brown’s campaign finance director, John P. Cook, wrote in an e-mail to supporters yesterday.
The campaign did not release an itemized list of contributors from the final quarter, which began Oct. 1. Those records are required to be made public the last day of this month.
Warren, a Harvard professor and architect of the federal Consumer Financial Protection Bureau, has not disclosed her final fund-raising figures for 2011.
“We will be releasing our numbers in the near future,’’ said Alethea Harney, Warren campaign spokeswoman.
In the weeks surrounding her announcement in mid-September that she would run, Warren collected more than $3.15 million from Democrats across the country, according to her third-quarter report.
Brown raised only $1.55 million for the same period, before his contributions swelled later this fall.
Sources on Warren’s fund-raising team say she is poised to equal that first financial report, demonstrating that she will be able to match Brown’s fund raising in a campaign that could help determine control of the US Senate.
“I have never had an easier time raising political money,’’ Philip W. Johnston, the former state Democratic chairman and veteran party fund-raiser said of Warren.
“It’s easier than raising money for [Edward M.] Kennedy,’’ he said.
In 2010, Brown drew red-hot national backing in the final weeks of his special-election campaign, raising more than $15 million to beat Attorney General Martha Coakley and fill the seat vacated by Kennedy’s death.
That victory, in what was then the epicenter of the national debate on universal healthcare, changed the country’s political landscape and rocked the Obama White House and the Democrat-controlled Congress. It also allowed Brown to become the focal point of GOP donors nationwide.
