(CNN) – Democratic Massachusetts Senate candidate Elizabeth Warren raised $6.9 million in the first quarter of 2012, more than doubling incumbent Republican Sen. Scott Brown's haul, according to her campaign.
Despite her fundraising advantage in the first three months of the year, Brown has $4 million more cash on hand heading into the 2012 election, at $15 million.

On Friday, Brown, the first term senator, reported bringing in $3.4 million.
However, Team Warren pointed to broad support for their candidate across the state with individuals from 350 cities and towns donating to the campaign. Eighty-three percent of donations since January 1 were of $50 or less, according to the campaign.
The two candidates are locked in a tight race in the typically blue state and statistically tied in recent state polling.
Warren, a former consumer protection advocate in the Obama administration, is the favorite to capture the Democratic nomination and face-off against Brown, who was elected during a special election following the death of longtime Sen. Edward Kennedy.
Non-partisan political handicappers Stuart Rothenberg and Charlie Cook list the race as a toss-up.
