Because Trump is a pro out of talking out of both sides of his mouth.
He's good at it, I'll give him credit.
And his disciples lap it up.
Donald Trump‘s number one claim to fame is his renowned negotiating skills and his successful record using those skills. Look it up.
He did it in business and he did it in the Oval Office—despite having to work with duplicitous politicians and bureaucrats out to get him. Kudos to President Trump.
