ANNOUNCER: She led the fight to open up markets for North Dakota oil. Republicans say she's "stronger than battery acid" and "interested in getting things done."

HEITKAMP: I'm Heidi Heitkamp and I approve this message, because when it comes to fighting for North Dakota I take battery acid as a compliment.
