Republican US Senator Scott Brown is not a “bad guy,’’ but “too often, on things that really matter, he’s not with you,’’ Democratic challenger Elizabeth Warren says in a new television ad released today.

“I’d be in there fighting for you, not some of the time – all of the time,’’ says Warren, who speaks for about a minute into the camera from a comfortable kitchen, complete with tea kettle and fruit bowl, in the background.

Warren — her tone measured — tells viewers that Brown “doesn’t always vote the wrong way.’’ But then she criticizes several of his votes, saying he voted against three of President Obama’s jobs bills, against “making millionaires pay the same tax rate as working families,’’ and in favor of giving hefty subsidies to big oil companies.


“Kids are drowning in student loans, roads need repair, the deficit is sky-high, and Scott Brown’s voting for giveaways to Big Oil? I wouldn’t do that,’’ she said.

The Globe reported last week that Warren advisers were mulling a new strategy aimed at toning down what top Democratic leaders described as a preachy tone that had had dominated Warren’sads. Her advisers had hinted that a new series of ads would also focus on Brown, saying that that while he is likable, he is not the moderate Republican he makes himself out to be.
