It goes this way:

Reporter: "Mr. President, Joe Biden says you are the first racist president. Do you care to comment on that?"

Trump; "No. BIDEN is the racist. I've done more for blacks than any president in history."

Then if pushed and he deigns to respond, he'll twist himself in pretzels trying to rationalize the first statement and then offer no supporting proof points for the second. He'll move on and no one will ask the question again or further press on it.

See how that works in Trumpland?

"Mr. Trump, your niece Mary Trump said in her book 'Too Much and Never Enough' that she heard you use racist language, including the 'N' word, many times. How do you respond to that?"

And a follow up question:

"Why did you remove Barack Obama's portrait from its previous place in the White House?"

And another follow up question:

"Why are you always, in every press conference, interview, address, etc., continuously flashing the white supremacy sign?"
