You’re good at labeling people you know nothing about. Eisenhower was definitely far too much of an Anglophile but I think you stretch things a bit by calling him a Communist. I’d say FDR was much more of a Commie.
It’s a joke. For all your political knowledge, you don’t know that fringe right-wingers called Eisenhower a communist in the 50s, and that we all laughed at them? *chuckle*
