The Shifting Map

The county-level political map of the United States has been redrawn multiple

times since Reconstruction. Counties that were reliably Democratic for a century

are now deep red. Suburban counties that anchored Republican coalitions for

decades have turned blue. Understanding these trends requires looking beyond

any single election.

156Years of county-level presidential data on Akashic Edge

Akashic Edge tracks presidential election results at the county level from 1868

to 2024 — 40 elections across 3,143 counties. This data reveals three major

realignment waves that reshaped American politics.

The Solid South (1868-1964)

For nearly a century after Reconstruction, the Deep South was uniformly

Democratic. Mississippi, Alabama, Georgia, and Louisiana counties voted

Democratic by margins of 80-90% in election after election. This "Solid South"

was built on white racial solidarity and one-party rule.

The 1964 Civil Rights Act shattered this alignment. Barry Goldwater carried

the Deep South, and counties that had been Democratic since 1868 began their

long march toward the Republican Party. By 2024, these same counties are

among the most reliably Republican in the nation.

Appalachian Realignment (2000-2024)

The coalfields and hollows of West Virginia, eastern Kentucky, and

southwestern Virginia represent the most dramatic county-level realignment

of the 21st century. These counties voted for Bill Clinton by 20-30 points

in 1996. By 2024, many vote Republican by 40-60 points.

The swing is staggering: individual counties shifted 60-80 points in a

single generation. Mingo County, WV went from D+35 in 1996 to R+57 in 2024 —

a 92-point swing.

The Suburban Inversion (2012-2024)

While rural America shifted right, affluent suburban counties moved left.

Orange County, CA — birthplace of the modern conservative movement — voted

Democratic in 2016 for the first time since 1936. Gwinnett County, GA —

Newt Gingrich's home base — flipped blue in 2020.

This suburban realignment is driven by education polarization: counties with

high college graduation rates have moved steadily Democratic since 2012,

regardless of region.
