A crowded field of Democratic candidates are vying to replace term-limited Democratic Gov. Janet Mills in Maine.
Dr. Nirav Shah, Maine’s former top public health official, is the front-runner for the Democratic nomination in recent polls. The other Democratic candidates running in the primary, which will be held with ranked-choice voting, include Secretary of State Shenna Bellows; former Senate President Troy Jackson; Hannah Pingree, the former Maine state House speaker, former director of the Governor’s Office of Policy Innovation and daughter of Rep. Chellie Pingree; and Angus King III, an energy executive and son of U.S. Sen. Angus King.
Jonathan Bush, a health care entrepreneur who is the nephew of former President George H.W. Bush and cousin of former President George W. Bush, officially launched his campaign for governor as a Republican on October 8. He joins a field of candidates that includes state Sen. James Libby, former U.S. Assistant Secretary of State Robert Charles, real estate executive David Jones and University of Maine trustee Owen McCarthy.
