There is no issue relative to hostility of the first Ku Klux Klan of the late 1860s and early 1870s towards the Republican Party, as it was seen as the party of the freedmen, white Southern Unionists, and Northerners who came to the South during the Reconstruction era. The second Klan that was founded in 1915 and reached its peak of popularity in the early 1920s was at least as strong in Republican leaning Northern and Western states as it was in the South. Many Northern Republican politicians were pro-Klan, including state officials in Oregon, Indiana, and Colorado and local officials in many other states. By the time the third Klan developed after World War II in reaction to the civil rights movement, few if any politicians endorsed it.

And what is your evidence for that conclusion?
