President-elect DONALD TRUMP already has a new campaign slogan…

…for re-election 2020: “KEEP AMERICA GREAT!” Eat your heart out, lefties. Will you put up Hillary Clinton again? Or your new favorite Muslim, Keith Ellison?

NY Post  Donald Trump hasn’t even been sworn in as president — but he’s already come up with his re-election slogan.

“Are you ready?” Trump asked a Washington Post reporter interviewing him at Trump Tower, seeming to have come up with the idea in the middle of the exchange. “‘Keep America Great,’ exclamation point.”

Trump, apparently happy with his decision, reportedly called for a lawyer.

“Will you trademark and register, if you would, if you like it — I think I like it, right? Do this: ‘Keep America Great,’ with an exclamation point. With and without an exclamation. ‘Keep America Great,’” Trump reportedly told his lawyer in the middle of the interview. “Got it,” said the lawyer.
