BOSTON — Political action committees and other outside groups are continuing to pour millions into Massachusetts’ U.S. Senate race.
To date, the groups have made more than $5.6 million in “independent expenditures” on the race.
An Associated Press review of Federal Election Commission reports found Democratic challenger Elizabeth appears to be benefiting from the bulk of the expenditures with groups spending about $3.6 million in support of her campaign.
Another $2 million has been spent in an effort to aid Republican incumbent Sen. Scott Brown.
The groups appear to be honoring a deal signed by Brown and Warren earlier this year designed to keep ads from outside groups off television, radio and the Internet.
Instead the money is going toward mailings, door-to-door canvassing, bumper stickers, signs, salary and automated phone calls – also known as “robocalls.”
