I am pretty sure the Republican party -- you know that pesky party that was founded on the premise of abolishing slavery -- rejects white supremacists. Ask former KKK Kleagle Byrd what party he preferred (D-WV).
The fact is that white supremacists are attracted to trump, more than any other modern presidential candidate. This is not a coincidence. They love his speech and words that divide, and that have overtones of hatred, bigotry, racism and xenophobia.
Regardless of what party trump is associated with, this fact holds water.
White supremacists are drawn to trump, like flies are to feces.
Have actual evidence of that claim? Just curious. Has the KKK vote been polled?
If you were to go onto Stormfront, I'd bet that you would find many, many Trump supporters.
