Elizabeth Warren, the presumptive Democratic nominee for Senate in Massachusetts, released a new ad today that continues to introduce the Harvard Law School professor and consumer advocate to voters.

“Her father was a janitor; my father was a janitor,” a woman says at the beginning of the ad.

“She’s one of us!” says a man, reflecting a sentiment seen at a recent Warren event with union voters.

The ad was rotated into an earlier buy of about $760,000 that ends May 20. It will also be part of a new significant statewide buy that will go beyond Saturday. Warren has had a substantial presence on Massachusetts TV in recent weeks.

Meanwhile, she has struggled to turn the page from a weeks-long controversy about her identifying as a Native American intermittently during her professional career.

Warren will face Sen. Scott Brown (R) in a tossup race this November.

“Big banks, institutions, Wall Street — she’s not afraid of anybody,” the woman says in the ad.
