Peoria's blend of industrial labor, downstate conservatism, and a mid-sized university has made it a reliable proxy for midwestern swing sentiment, though its bellwether streak showed cracks in the 2010s as rural-urban polarization deepened.
Across the recorded series it reached a Democratic high of 26.2 points in 1912 and a Republican high of 40.2 points in 1920. Between 2020 and 2024 the metro moved 1.9 points toward the Republican candidate; the 2024 margin was 15.1 points.
A population of 365,202, a 79% non-Hispanic-white share, and a median household income of $72,642 describe the metro. The metro's voting pattern over the last decade is most similar to that of Louisville/Jefferson County, KY-IN and Kansas City, MO-KS.
