CORALVILLE — Continuing his month-long campaign across the state in anticipation of its first-in-the-nation caucuses next month, Republican presidential hopeful Mike Huckabee on Tuesday made five stops in Eastern Iowa, reminding voters along the way of his surprise victory in the contest eight years ago. “You have not just an opportunity, you almost have an obligation to do something that would be remarkable,” Huckabee told a crowd of more than two dozen people Tuesday in the American Legion Post in Coralville.
