Holy moly, Dwight Eisenhower was not a liberal. This is the strangest revisionism of them all.
You know how hardcore conservatives like Cruz call people like Kasich "RINOs" because they aren't quite as extreme as the "true conservatives" would like, but Democrats laugh at this because both are conservatives at the end of the day who simply disagree on method and pragmatism? Insert Goldwater and Eisenhower instead.
You do know Ike didn't run in 1960, right?
He was talking about 1952 and 1956, which are also on the list.
