Warren's haul seems to confirm her growing reputation as a fundraising juggernaut. Warren nets $1M in a single day

Elizabeth Warren raised more than $1 million in a single-day fundraising "money bomb" Thursday.

The event was timed to coincide with the official launch of Mass. Sen. Scott Brown's reelection campaign and the anniversary of the 2010 special election that turned the late Sen. Ted Kennedy's seat over to Republican hands. Indeed, the Warren campaign hit the $1 million mark at around the same time that Brown was delivering his announcement speech in Worcester, Mass., Thursday evening.

Warren's $1 million event came on the heels of an impressive $5.7 million fourth-quarter fundraising haul, and seems to confirm the growing consensus that she is a fundraising juggernaut. Warren previously notched a $3.15 million third-quarter total — an astonishing number given that she had only been in the race for six weeks.

By the end of the day Thursday, the campaign brought in more than $1,194,000.

"Today the message is clear: We have the grassroots momentum and enthusiasm to take the 'people's seat' back from Wall Street and other powerful interests," Warren told POLITICO in a statement. "I am grateful for this show of support and will keep working my heart out for the small businesses and middle class families who deserve someone on their side in the Senate."

The Warren camp insists that the Harvard professor and consumer advocate will be outgunned by Brown's millions and a flood of "Wall Street" cash from Republican outside groups like the Karl Rove-backed American Crossroads and the U.S. Chamber of Commerce.

Though Warren outraised Brown in the fourth quarter, he still holds a nearly 2-to-1 cash advantage.

The Warren campaign and other Democrats are seeking to tap into a groundswell of support from those sympathetic with the anti-Wall Street message popularized by the Occupy Wall Street movement. Her pitch to supporters on Thursday suggested that the money raised would serve as a counterweight to the influence of "Wall Street" money in the campaign.

"What we accomplish together today will show the world we have the grassroots organization and support to win this election, no matter what Scott Brown and Wall Street throw at us," Warren wrote in a message to supporters this week.
