Sabato: RNC Convention Unlikely to Move Midterm Needle

Larry Sabato, founder and director of the University of Virginia Center for Politics, says next week's Republican midterm convention, headlined by President Trump, is unlikely to reshape the dynamics of competitive House races. He also discusses the legal fight over Missouri's congressional map and the dispute over mail ballots in North Carolina. He speaks with Kailey Leinz and Joe Mathieu on Bloomberg's "Balance of Power."
