I'd say the most moral of them all were the Obamas and the Carters (Jimmy & Roslynn Carter) The Carters the most commendable of all.
I watched a partial showing of Jimmy Carter's Presidency, and found out all kinds of things I had no idea of before.
He actually was ahead of his time on the Climate change issues and even put solar panels on the rooftop of the White House which were removed by the Reagans.
There were other accomplishments which we never got wind of, I'll need to see if I can find them when I have the time.
Here is a little about his new biography:

They used all their lengthy retirement years working for Habitat for Humanity. True moral folks who walked the talk.
The rest of them you can put into a paper bag, shake it up, see which falls out, they are all alike imo.
