That is obviously an ideal situation, but in the real world does it matter?How about we elect competent Presidents with character and integrity that nominate well-qualified, unbiased judges without skeletons in the closet?
FDR did not have a perfect past but he got the New Deal through.
JFK shagged his way through his presidency but it didn't stop him saving the world from nuclear disaster in 62.
Clinton got a BJ in the oval office, but he was a very empathetic president nevertheless.
Trump is a loud mouth who makes unnecessary trouble for himself , but he is tackling many issues that have long been considered too hot to handle by other presidents. He is also up for a Nobel Peace prize for making peace with NK, in case you hadn't noticed.
Obama got the peace prize just for being elected, which must have been embarrassing for him to be honest.
I learned the lesson from history, that the right things can still get done by imperfect people. Many people reform themselves and become older and wiser as they mature. If we all stayed as dumb and insensitive as we were as kids, the world would be like the "Lord of the Flies".
