 Oklahoma came into being as a state at the height of the era of Jim Crow Laws and had a Ku Klux Klan presence in the 1920s.Race politics gave way to Democratic political infighting over the New Deal in the 1930s and 1940s and the gradual growth of the Oklahoma Republican Party's power.Today, most of Oklahoma's federal and all of its statewide offices are all held by the Republican Party, which also holds supermajorities in both chambers of the state Legislature.
