Thatcher?
Exactly. TR was infatuated with Socialism (and helped elect hardcore Socialist Wilson in 1912). Nixon may have been anti-Communist, but he also did nothing to promote Conservative policies as President, and, in fact, expanded and implemented leftist policies across the board (all the more astonishing that the left still hated him with a passion despite his expansion of Socialism).
Ah-nold in California, whom I exposed as an absolute fraud 19 years ago during his run for Governor, was also a hardcore Socialist married to a Kennedy and whom destroyed most of what was left of the CA Republican party. He remains an embittered RINO leftist today and one of the worst Governors in CA history, certainly the worst that ever claimed to be a Republican. His leftist Demonrat predecessor that he ousted in the recall was to his right.
