Throughout the 2016 US election, AFP will be meeting some of the Americans who make up the many Voices of the Campaign. The Gragert brothers and their friend Aaron are caucus tourists who've made a 1,000 mile round trip from Wisconsin to attend the political rallies being held in the run-up to the Iowa caucuses. The trio did the same thing in 2012, saying it's a great opportunity to meet national-level politicians, one of whom will become US president.
