Of course, his past affiliation with the racist and terrorist Ku Klux Klan are being...excuse the metaphor...whitewashed. At least former President Bill Clinton did talk about it, excusing is merely a ploy to get elected.
Be that as it may, the KKK was a horrible organization and a stain on our nation's past.
However, that makes it fair game for political humor satire. The '60s folk group the Mitchell Trio sang about them in a number titled "Your Friendly Liberal, Ku Klux Klan." FYI, the tenor in the group is the late John Denver.
