Dwight Eisenhower. He was a moderate who really should have just been an Independent. I think he was underrated - a very respectable, distinguished man, and he was extremely qualified to serve as Commander in Chief.
Eisenhower was more pragmatic than he was moderate. He was partisan enough of a Republican that the disclosure of his previously unknown political views pretty much ruined his friendship with Truman.
Anywho, Biden. Think the guy is a bit off these days, but he’s not a “horrible person.” The people who pretty much dictate what his policies will be are much worse.
. Truman didn't object to Hoover despite similarly different views. It wasn't then mere view differences, but something else. Hint, Ted Cruz's double.
