It had well-documented ties to Democrats and Republicans alike.
Anyone insisting otherwise is either ignorant or lying.
I did a thread about it here, after reviewing Linda Gordon's recent book on it all:
In the South, the KKK was overwhelmingly aligned with the Democrats.
But in other parts of the nation -- especially places where Democrats were linked to Catholics and immigrants -- the nativist Klan sided with the GOP.
It had arguably the strongest Klan presence of any state, and the Grand Dragon there was a Republican who exercised tremendous influence in (and brought a huge scandal to) the state GOP.
See this thread on the facts & fictions of the Democrats' "Klanbake" and the Republicans' "Kleveland Konvention"
Such a claim would be just as willfully dishonest as the claim that the Klan was exclusively tied to the Democrats.
It's not a new point. I stressed this in my review of Linda Gordon's The Second Coming of the KKK two years ago.
Because if you did that, you'd just come off like an embarrassing partisan hack.
