Hmmmmmmmmmm...one AH writer suggested (possibly jokingly) in a published AH that McCarthy could have been a communist plant. Perhaps Reagan may actually have been a Communist plant whose nudging America to the Right, so as to make Communism more palatable was too successful?
(Ironically, at least one obscure right-winger wrote at least two book lambasting Reagan as a liberal. One's title was "Here's the Rest of Him", a pun on Reagan's own autobiography...
Here's one reviewer's take on a later book on Reagan by that guy, entitled "The Counterfeit Candidate"...

Sadly, I think that the guy who wrote that would be a fixture on the Tea Party speaking circuit now.
