Joe Biden has filled out his senior Iowa leadership team as polls show a competitive race in a state President Donald Trump won handily in 2016.

The Democratic nominee and former vice president announced Friday that Jesse Harris and Iowa state Rep. Ras Smith will serve as strategic advisers to the campaign, Ellen Goodmann Miller will be its deputy political director and Lanon Baccam will be its deputy state director.

Those four join Iowa state director Lauren Dillon, who directed U.S. Sen. Amy Klobuchar’s Iowa caucus campaign, and senior adviser Jackie Norris, a former president and CEO of Goodwill Industries of Central Iowa and director of Barack Obama’s 2008 Iowa general election campaign.
