Democratic Senate hopeful Warren unveils new TV ad

BOSTON (AP) -- Democratic senate hopeful Elizabeth Warren is taking aim at Republican U.S. Sen. Scott Brown for the first time in a new television ad.

The 30-second ad features gym owner Art Ramalho who helped train Lowell native Micky Ward, whose life story was the inspiration for the film "The Fighter," starring Boston native Mark Wahlberg.

In the ad, Ramalho calls Warren a real fighter and says Brown has been "siding with the big money guys" and big corporations.

It's the first time that either candidate in the closely watched race has named their rival in a television ad.

The ad marks a shift from earlier Warren ads, which some in her party criticized as ineffective.

Brown sent out a fundraising letter Thursday saying he needs to be prepared for whatever attacks Warren is preparing.
