Who is to blame.

That's not what the slanderers are doing. They are saying that all voters for one candidate must always share the same values and reasons for supporting that candidate.

Some do, some don't. But if the KKK is vocal about their support for a certain candidate it should give everyone pause. Takes a pretty advanced level of apathy to take note of that and still go out to cast one's vote because the same candidate gives the appearance of also supporting some pet value of theirs.

The KKK didn't support any republican or democrat candidate after WWII so far. This is a first and it conveys the message of them feeling represented. If someone is comfortable with still taking the ride, they at least don't mind.
