Barry County has delivered double-digit Republican presidential margins for decades, and its 2024 result of R+34.3 reflects a largely white, small-town electorate concentrated around Hastings with minimal urban counterweight.
The Republican margin in Barry County reached its widest at sixty-one points in 1928. The margin in 2024 was thirty-four points, in line with the county's deep historical pattern.
Barry County's loyalty is rooted in its place. Median household income of $77,500, a 93% non-Hispanic-white share, and a population of 63,409 together describe a community whose political habits are deeply settled. The county's voting pattern over the last decade is most similar to that of Noble County and Lyon County.
