Sen. Scott Brown of Massachusetts still holds about $2 million more in his campaign coffers than Elizabeth Warren, but his lead has narrowed over the last three months as he raised just $5 million compared to $8.5 million brought in by his Democratic opponent.
It was Mr. Brown’s most successful fundraising quarter yet as he seeks to ward off a tough challenge from Mrs. Warren, a Harvard professor who built her reputation in Washington as a consumer watchdog over the 2008 bank bailouts.
But he didn’t haul in nearly as much as Mrs. Warren, who set her own new fundraising record and now holds $13.5 million in her war chest. Mr. Brown has about $15.5 million in the bank, assisted by funds left over from his 2010 election.
Mr. Brown’s campaign said that two-thirds of his donations came from Massachusetts donors, compared to Mrs. Warren, who has drawn from outside the state for a majority of her funding.
The race keeps climbing toward becoming the most expensive Senate race in history, with the candidates together raising nearly $50 million with the latest reports. The record is currently held by the 2000 New York U.S. Senate race between Hillary Rodham Clinton and Rick Lazio, who pulled in a combined $70 million.
