Yes, and plenty.
“At the time of
Ulysses S. Grant's election to the presidency, white supremacists were conducting a reign of terror throughout the South. In outright defiance of the Republican-led federal government, Southern
Democrats formed organizations that violently intimidated blacks and Republicans who tried to win political power.
The most prominent of these, the Ku Klux Klan, was formed in Pulaski, Tennessee, in 1865. Originally founded as a social club for former Confederate soldiers, the Klan evolved into a terrorist organization. It would be responsible for thousands of deaths, and would help to weaken the political power of Southern blacks and Republicans.” -the American Experience, PBS

Do you want a partial list of Democrats that were members of the KKK?
Here you go:
Edward Douglass White, a Democrat and the
Chief Justice of the United States, was a known member of the KKK in his home state of Louisiana, where he had served a U.S. Senator.
Hugo Black. In 1921, he successfully defended
E. R. Stephenson in his trial for the murder of a Catholic priest, Fr.
James E. Coyle. Black, a Democrat, joined the Ku Klux Klan shortly afterwards, in order to gain votes from the anti-Catholic element in Alabama. He built his winning Senate campaign around multiple appearances at KKK meetings across Alabama. News of his membership was a secret until shortly after he was confirmed as an
Associate Justice of the United States Supreme Court.
Theodore G. Bilbo, a Democrat, the
Governor of Mississippi and later the U.S. Senator for Mississippi, was a founder of the Mississippi chapter of the KKK.
John Brown Gordon, a Democrat and the U.S. Senator for Georgia, was a founder of the KKK in his home state of Georgia.
Elmer David Davies, a Democrat and a Federal Judge of the
United States District Court for the Middle District of Tennessee, was a member of the KKK whilst at university.
Bibb Graves, a Democrat, who was the
Governor of Alabama. He lost his first campaign for governor in 1922, but four years later, with the secret endorsement of the Ku Klux Klan, he was elected to his first term as governor. Graves was almost certainly the
Exalted Cyclops(chapter president) of the Montgomery chapter of the Klan. Graves, like Hugo Black, used the strength of the Klan to further his electoral prospects.
I could cite many more.
Yes, the Democrats have a history of being the party of the KKK.
