Franklin County, tucked in Indiana's southeastern corner, recorded an R+64.4 margin in 2024 — among the widest in the state — reflecting a rural, small-county electorate that has shifted decisively toward Republican candidates over the past two decades.
The Republican margin in Franklin County reached its widest at sixty-four points in 2024. The margin in 2024 was sixty-four points, in line with the county's deep historical pattern.

Median household income of $78,074, a 96% non-Hispanic-white share, and a population of 23,020 together describe a community whose political habits are deeply settled.
