2010 Oklahoma elections

The 2010 Oklahoma elections were held on November 2, 2010. The primary election was held on July 27. The runoff primary election was held August 24.

The Republican Party swept every statewide election and expanded its majorities in both state legislative chambers. An extremely socially conservative state, Oklahoma has not voted Democratic in a presidential election since 1964 but remained reliably Democratic at the state level well into the 2000s. This election marked a new and decisive alignment in the state's partisanship at all levels of government, with the GOP continuing to make gains in almost every election since.
