Harvard Professor and consumer advocate Elizabeth Warren is tied with Sen. Scott Brown in a new poll, as Wall Street gears up to undermine her campaign.

But don't expect the opposition to be in the form of massive donations to Brown. Financial industry executives are worried that by overtly attacking Warren, they risk boosting her chances with an electorate unfriendly to banks, POLITICO reported, but they are considering less public methods to weaken her position.

Warren, who led the charge in creating the Consumer Financial Protection Bureau, was the target of frequent assaults from the financial industry that prevented her from taking the helm of the agency — and the same lobby fears what she would do in the Senate if she defeats Brown.

Brown voted for Dodd-Frank, a transgression likely to be overlooked with Warren soaring in statewide polls. A new UMass-Lowell/Boston Herald shows Brown leading Warren 41-38, within the 3.8 percent margin of error.
