Former KKK Grand Wizard David Duke Calls GOP Rep. Scalise a Fine Family Man
If Duke says so, certainly Scalise is not a racist.
And obviously voting against MLK day is a good sign as well

Months after criticizing Duke, he was one of six state representatives who voted against making Martin Luther King Jr. Day a state holiday. He had also voted against a similar bill in 1999.
In 2011, Scalise endorsed then-state Rep. John LaBruzzo's re-election campaign in the district that had once been represented by Duke. He did so despite the fact that just three years earlier, LaBruzzo, a Republican, got into hot water for proposing to pay poor women to be sterilized or otherwise to not have children, while rich, better-educated women could be given incentives to reproduce.
