Warren looks to punch back on economy with new ad targeting Brown

Elizabeth Warren is looking to punch back at her opponent, Sen. Scott Brown (R-Mass.), with a new commercial that touts her economic recovery plan. 

The ad, which argues for additional spending on infrastructure and education, is intended to counter a spot released by the Brown campaign earlier this week that linked Warren to President Obama's "you didn't build that" comment. 

Republicans have criticized both Obama and Warren, arguing they believe too heavily in government's economic role and do not properly acknowledge the efforts of entrepreneurs.

But in the Warren ad, the consumer advocate and Harvard professor argues her plan is the best way to jump-start the American economy.

"We’ve got bridges and roads in need of repair, and thousands of people in need of work," Warren says in the ad. "Why aren’t we rebuilding America?" 

Warren goes on to note that American spending on infrastructure lags significantly behind competitors, including China. 

"We can do better. We can build a foundation for a strong new economy and get people in Massachusetts to work right now," Warren said.

The Warren campaign did not say how much they planned to spend on airing the new ad.

The Massachusetts Senate race has been one of the most competitive of the year, with Warren and Brown both proving to be popular — and potent fundraisers. A poll released earlier this month by MassINC showed Warren ahead, 40 to 38 percent, within the survey's margin of error.
