Rural voters were key in helping Donald Trump win the presidency in 2016. The divide between these communities and urban areas continues to grow, with rural America becoming increasingly conservative .

Democrats know they have work to do to win over some of these voters, and theyre starting out in Iowa. Even though the states first-in-the-nation caucus is still about a year away, the Democratic presidential candidates have already made dozens of trips to the state.
