Senator Scott Brown and Elizabeth Warren released new television commercials Wednesday amid a quickening rotation of spots airing on Massachusetts stations.
Brown, the Republican incumbent, released the third in a series of testimonials from Democrats who say they are backing him because of his bipartisanship.
“We need a person like Scott Brown that’s going to say, ‘I don’t care whose idea it is. I don’t care if it’s left or right, Democrat or Republican. This is a good idea; it’s going to help people that are suffering,’ ” Paul Walsh, a former district attorney in Bristol County, says in the ad.
Previous ads in the campaign featured Raymond L. Flynn, the former mayor of Boston, and Konnie Lukes, the former mayor of Worcester.
Warren’s ad focuses on student loan debt, a topic she has explored in some of her books.
“America ought to be investing in education and building a future for our kids,” Warren, a Democrat and Harvard Law professor, says in her spot, which shows her greeting college students. “But Washington’s giving billions to big oil and tax breaks to millionaires. . . . Washington needs to get its priorities straight.”
Another recent commercial focused on Warren’s belief that the United States should spend more on infrastructure.
While Brown and Warren have signed a pact that forces them to pay a penalty if they benefit from third-party ads aired on their behalf, both candidates have plenty to spend on their own.
Their most recent fund-raising reports showed Brown with $15.5 million cash on hand and Warren with $13.5 million.
Those bulging war chests mean voters will not get any respite from the onslaught of ads, which are expected to flood the airwaves in the runup to the November election.
The race is already the most expensive congressional contest in the country and has drawn money and attention from activists in both parties because it could help determine the balance of power in the Senate in 2013.
