No. While Taft was more conservative than Eisenhower, Ike was not the underling of Dewey as he is sometimes portrayed. The difference was that Taft wanted to rollback the New Deal, which was obviously politically impossible. Eisenhower was content to leave the New Deal together while he focused on foreign affairs, but he resisted LBJ's attempts to expand it numerous times.
So he's a conservative that didn't really do much of anything conservative in his eight years in office. Gotcha.
He was a moderate then and he's very moderate now. He certainly wasn't conservative.
Opposing progressive legislation is not conservative? This is the same Eisenhower who warned of "creeping socialism" during his campaign. Is the only way to be conservative to roll back the New Deal? Then I'm sure you will happily accept George Bush and Richard Nixon into the liberal ranks.
That Eisenhower did not accomplish during his presidency what are "conservative goals" does not mean anything. He was content with running foreign policy and what little oversight he did give over domestic issues was mostly concerned with heading off LBJ.
Sorry man, building roads is not just a liberal position.
