Being clever and being intelligent are not the same.
Some people are clever with their hands: woodworking, crafts, etc.
Some are clever at persuasion: salespersons, debaters ... and conmen.
Donald J. Trump is not an intelligent man. His spoken words and tweets have established that independently of anyone else's opinion. But he must be considered the cleverest man in all history because he conned the most powerful country in history into making him its president.
Mitt Romney - - for whom I am virtually certain 99% of Trumpers voting in 2012 voted - - acknowledged as much when, on Mar. 3, 2016, at the University of Utah, he said:
"Donald Trump is a phony, a fraud. His promises are as worthless as a degree from Trump University. He's playing members of the American public for suckers: He gets a free ride to the White House, and all we get is a lousy hat."
Romney further implored Republicans to reject Trump's candidacy in an election "that will have profound consequences for the Republican Party and, more importantly, for the country."
Often it is said: "There are two sides to every story." Well, what if I knew only Trump's side? In fact, what if I knew nothing that ANYONE, including Romney, had EVER spoken or written about Trump - - all I knew were the words that came out of Trump's mouth and those he's tweeted. ...
I would have nothing to do with the guy. I wouldn't go into business with him. I wouldn't buy a used car from him. I wouldn't have a cup of coffee with him. If he walked into the room I'd leave immediately ... based solely on his own words.
How is it that some folks can spot a conman from his first sentence, yet other folks gobble him up? "There's a sucker born every minute." Words speculatively attributed to P.T. Barnum, now considered by many to be the second-most-famous conman in world history.
