Did disillusionment with Eisenhower and the 83rd Congress lead William F. Buckley, Jr. to start the National Review?
I mean, to some extent. My understanding is that it was more a general feeling that American conservatism had atrophied and surrendered, so while Eisenhower embodied in many ways that surrender of the GOP to the "liberal consensus" that Buckley and others saw as dominant, he was by no means the only or even the major factor. National Review did endorse Eisenhower in 1956, but did not endorse in 1960, so I do think there was frustration with the Eisenhower administration, but I think the desire to create a publication like National Review preceded the Eisenhower administration and had much more fundamental and deep seated origins.
