Democratic Presidential Hopefuls Woo Iowa Voters Ahead of 2020 Caucus Kane Farabaugh IOWA CITY, IOWA - It's the final days of the campaign for Democratic presidential hopefuls to win the hearts and minds of voters in Iowa, but so far none of the candidates still in the race have earned University of Iowa student Nick Pryor's support. "Ah, I'm still undecided at this point," he told VOA during a break in his studies as a political science major. The Feb. 3 "first in the nation" Iowa Caucuses will also be the first opportunity for 20-year-old Pryor to participate in a presidential selection event. But who he ultimately picks won't be his first choice. "I started volunteering, helping out in the (U.S. Senator) Cory Booker campaign," he said, his voice indicating some resignation. "Unfortunately, he dropped out." Now, Pryor is researching which candidate will best address his biggest concerns -- curbing soaring college tuition costs, and protecting the environment. "I've narrowed it down already to Senator (Elizabeth) Warren or Senator (Bernie) Sanders," he said. .
