applicant Donald Trump

It's obvious from his performance applying with voters for the job of POTUS, the side of the desk that Donald Trump has always been on in job interviews. 

Can you imagine an applicant ever getting the job--any job--with Donald Trump's complete lack of tact?

Being POTUS requires some diplomacy--not only with foreign leaders; but also, with U.S. citizens, and even enemies. Donald Trump is clearly unqualified to be POTUS. 

"You're fired!" would never happen with applicant Donald Trump--he'd never be hired in the first place.
