Mr. Trump was a highly successful Reality Television star....that's great.  I'm pleased for him.  He became that star by being exceedingly arrogant and exceedingly nasty to people.nastiness plays well on Reality Television. However, he's now transferring that same personal arrogance and that same nastiness to a campaign to become President of the United States.  Amazingly, millions of folks seem to feel that, somehow, being President is akin to being a Reality TV star. 

IMO, Donald Trump is the least qualified (intellectually, emotionally and morally) candidate in the fifty-two years I've been casting my ballot for the office of the President of the U.S.  I've voted for successful candidates and I've voted for unsuccessful candidates.  Over my 74 years our nation has had its "ups and downs", its good times and bad times, during the presidencies of candidates I've voted for and those I voted against. 

Trump is the first candidate I've viewed as a true threat to our nation's welfare
