Not that these men are the same, but the similarities seem to indicated the characteristics you mention are not necessary or specific to being “Presidential” including for those who seek such office as a conservative...
Just a thought....
Ronald Reagan had been out of hollywood YEARS after deciding to run for President. I don’t like the fact that he was divorced, but I was too young to vote at that time. I don’t know who was running against him in the Republican primaries.
Not only that, but I believe the man in question was also at one time, a democrat, and a union head!
