WASHINGTON — Sen. Bernie Sanders launched his first presidential campaign ad Sunday, highlighting his journey as a Brooklyn kid who turned into a thorn in the side of Wall Street — and one who’s now ready to take on chief rival Hillary Clinton.

“People are sick and tired of establishment politics and they want real change,” Sanders tells a crowd featured in the $2 million one-minute ad buy that will air over the next 10-days in Iowa and New Hampshire.

The ad, called “Real Change,” draws distinction between himself and Clinton on key issues—his opposition to the Iraq War, his plan for tuition-free public colleges and branding himself an “honest leader.”

And it highlights Sanders’ civil rights activism in the 1963 March on Washington with an image of Dr. Martin Luther King, Jr. and record of accomplishment as mayor of Burlington, Vt.

“The son of a Polish immigrant who grew up in a Brooklyn tenement,” the narrator says over images of the Statue of Liberty and a young Sanders. “He went to public schools, then college, where the work of his life began: fighting injustice and inequality. Speaking truth to power.”

“Now he’s taking on Wall Street and a corrupt political system,” the narrator says.

After a solid debate performance and official exit of Vice President Joe Biden from White House consideration, Clinton now leads in Iowa and cut into Sanders’ advantage in New Hampshire.

Sanders is fighting back by spending some of the $11 million in his war chest to humanize himself.

The spot introduces his family to voters, and ends with, “Bernie Sanders. Husband. Father. Grandfather.”
