Trying to tie the KKK in with the Democrats, hm? Nice try, but no seegar for you, sir. Time was when that was very, very true - when the very, very conservative South was solidly Democratic - the Democratic "Solid South", it was. But after the Civil Rights Act, the racists in the South began to blame the Dems...and Nixon took advantage of it with his "Southern Strategy"...
...and the KKK was always, always a conservative group.
FYI - I'm well aware of all this because I grew up in the very deepest of the Deep South - the MS Delta - in a racist family, and I was racist myself - my family were Democrats until Nixon came along, and from then on we were Republicans. Thanks to the Navy forcing me to unlearn the racism that I and almost every one of my fellow whites that I knew had been taught since birth.
So keep your KKK-Dems crap to yourself - your claim is either disingenuous or made out of sheer ignorance.
Back then, there were liberals and conservatives in both parties...but now, there's a few conservatives in the Democratic party, and liberals are scarce as hen's teeth in the GOP.
