Over the last 227 years, that has overwhelmingly been the case with both success and failure, with obviously most being successful. Over those 227 years, there have only been 11 presidents that were not either lawyers, or career military. Of those only two were businessmen, but they both held elected office prior. They are Bush Sr. and Jr. How well they did at the job is seriously debatable.
In those 227 years, only 4 presidents have come to power without serving as an elected official previously. Taylor, Grant and Eisenhower all were career military prior. Hoover was only Secretary of Commerce prior under Harding and Coolidge, so not elected. He also was the only engineer to be president and sadly, was considered to be a pretty lousy president. The only other president that came to power with little previous experience was Chester Arthur. He was elected to Vice President of the US under Garfield and served in that position for only a year before Garfield was assassinated and he became president. He was of course though, a lawyer.
So maybe we have been insane and getting it all wrong for the last 227 years. IDK. However I see nothing at all presidential about Trump. I see no qualities in him that make me think he would be any good at the job and he has no experience at all as an elected official. Voting for him just because "He's not one of them." seems poor logic too me. Also, I felt (both times) that Obama was an incredibly poor choice and that a large number of people voted for him for the wrong reasons too. I hope we can vote this time in a more analytical way rather than emotion.
"Well, we've always done it that way, so no need to change now"...........
Seriously?
Put another Washington politician, another party "elite" or a career politician in and the voter gets the government he deserves.
Career politicians and party loyalist have got us in this mess. It's time to think "outside the box".
