CloseThere are just weeks to go until the US midterm elections that will decide control of Congress, with campaigning in full swing around the country and voters weighing who to back at the ballot box.
The elections will have a potentially major impact on the remainder of President Donald Trump's time in office. He is facing challenging political headwinds with concerns over rising costs and the war in Iran high on the minds of voters.
Ahead of the elections, the BBC's Sarah Smith travelled across Iowa to speak to voters in the predominately Republican state.
Produced by Cai Pigliucci, filmed by John Landy and edited by Blanca Estrada
