Liberal Eisenhower, since that's the false one.
Raised taxes to 90%, lots of infrastructure, kept New Deal programs, put Earl Warren into the SC, warned against the military complex...those are some pretty good arguments without context.Without context, of course. As shua said, no one was paying that, and the effective tax rate was absolutely lower back then. Eisenhower also helped lower it. His biggest infrastructure achievement, the interstate highway system, was quite literally defense spending, something liberals are not so fond of in excess. He didn't have a lot of say in getting rid of New Deal programs given their popularity and his Congress, but he privately expressed a lot of discomfort with the size of government post-New Deal. Most of Earl Warren's "liberal" reputation seems to be from his decisions on civil rights, and even if you subscribe to the idea that supporting individuals' civil rights is some inherently "liberal" view (I do not), most Northern conservatives in the GOP agreed with that viewpoint, so it certainly didn't add to Eisenhower's reputation as a "liberal."
Ike was, above all else, a pragmatist. From what I have read on him, however, he was privately quite conservative.
