Louisville-Jefferson County merger (2003)
The city of Louisville and Jefferson County merged governments, replacing a patchwork of separate jurisdictions with one metro government and a 26-seat council elected by district.
Democrats won the council majority in the first election and have held it since.
The merged structure became the baseline that local Republicans described in 2026 as the political order they wanted to disrupt.
The Republican plan was explicitly aimed at breaking a majority that has survived every election since the merger.
