(CNN) - Democratic candidate Elizabeth Warren pulled in $5.7 million for her Massachusetts Senate bid in the last three months, her campaign announced Wednesday.
Her fourth quarter fundraising outpaced the incumbent, Republican Sen. Scott Brown, who earlier this week reported raising $3.2 million.

The two candidates are considered strong front-runners in their respective parties ahead of the state's Senate showdown in November.
Widely expected to be a toss-up, the race has already heated up with both campaigns and outside groups running ads and web videos.
Warren, a former adviser to President Barack Obama during the formation of the Consumer Financial Protection Bureau, took out $1.6 million in television ad buys last month, alone.
For the last three months, her campaign reported the average contribution totaled $64 and boasted a contributor list of about 23,000.
While Warren raised more than Brown in the final quarter, her September entry into the race put her $6 million cash-on-hand numbers well short of Brown's $12.8 million war chest.
Responding to Wednesday's fundraising figures, the Massachusetts Republican Party issued a statement calling into question the source of Warren's haul.
"Elizabeth Warren is being financed by extreme liberal special interests from outside Massachusetts," the statement read. "As the intellectual founder of the radical Occupy protests, she has a national network of left wing supporters eager to open their wallets to finance her agenda of bigger government, higher taxes and more debt."
Massachusetts Democrats blasted Brown's fundraising figures Monday, calling them a result of big bank financing.
"It's no surprise that Wall Street and the big banks continue to finance Scott Brown's campaign because he continues to put their interests first, ahead of middle-class Massachusetts families," Kevin Franck, a Massachusetts Democratic Party spokesman, said in a statement.

I think she looks fine! A very trustworthy countenance, in my opinion.
Ms. Warren is a true champion of the 99%. This outstanding individual has stood up to Wall Street (and Republicans) with honesty, dignity and strength. I wish she was running for election in my state.
Mass, please vote for Elizabeth Warren. She stands for poor, Middle-Class. Not for Card-holder-Banking-Greed. Every time you swipe your visa/m/c Banks make money and they charge you....Watch out the Greedy GOPigs.....Obama12
I think Ms. Warren look fine the way she is. She dont need to look phony like sara and michele
"Intellectual founder?" What the hell is that? She didn't call on people to protest Wall Street. She tried to start up a consumer advocate office, but the Republicans tried every trick in the book to stop her confirmation. So are the Republicans trying the throw $h!t against a wall and see what sticks tactic?
Warren 2016! Replace the pretty boy. Bring some knowledge to DC.
