Hoover was a progressive technocrat and Ike, were he alive today, would be described for many reasons as a RINO. Ike could well have run as a Democrat (of that era) but ran as a Republican in part because of his personal concern that the US was becoming a one party monopoly. His opposition was the Conservative wing of the party led by Sen. Bob Taft. Reagan fits the bill as a genuine “movement” Conservative, but other than him one has to go back to his favorite president, Calvin Coolidge.
