Wage and price controls, affirmative action, the EPA, and on and on, make him at least an anti-republican statist, if not a modern day liberal.

And there it is. Nixon was predecessor to a political group known today as the neo-conservatives. Typical of political doublespeak, there is nothing conservative about a neo-con. Nixon and both Bushes were/are global socialist in economic and political alignment. A better name for them might be liberal hawks.
I expect Nixon's image will continue to be "reformed" over time as the left gets past the context of its visceral hatred for everything Republican and starts realizing Nixon did more for their agenda than any of his successors until the Bushes.
