Warren also touts her work on consumer protection issues. "For years I worked to expose how Wall Street and the big banks are crushing middle class families," she says. "I led the fight for a new agency to protect consumers -- and we got it. But Washington is still rigged for the big guys. And that's got to change."
While Warren's campaign isn't commenting on the size of the ad buy, "It's a statewide buy that's aimed at allowing Elizabeth to tell her story and explain her fight to the people of Massachusetts," said her spokesman Kyle Sullivan.
The race is expected to be extremely expensive: Warren took in over $3 million in her first fundraising quarter, and Brown reported $10.5 million in the bank as of September 30.
