Bullock launched his first full day of campaigning Friday in Newton, Iowa, a town where union manufacturing jobs have vanished in the past 15 years. In doing so, he is underscoring his argument that his party can win in 2020 only if they show voters, especially in Middle America, that Democrats understand their economic concerns.
