We may need a category named “Why Bother?” for this one, because the guy who’s currently in first place in the GOP presidential field because the right wing base loves his outright xenophobia and racism has just fired a staffer for… outright xenophobia and racism.

Sam Nunberg allegedly wrote racially charged and disparaging political posts dating back to 2007, including one calling civil rights leader Rev. Al Sharpton’s daughter a “N—!” and another calling President Barack Obama a “Socialist Marxist Islamo Fascist Nazi Appeaser,” Business Insider reported Friday. Nunberg is denying he wrote the posts.

Nunberg’s attempt to deny he wrote the posts is noteworthy for its sheer incoherence:

“I am not adept at social media,” he told CNN on Friday. “I have a long record of working with diverse people. And anything you are reporting on does not reflect anything on Mr. Trump or Mr. Trump’s campaign. I would also point out that all of these things were done before Mr. Trump’s campaign, if I even did them — which I deny. In any event, this is the problem with politics … Politics as usual is wrong.”

Lolwut?
