Reagan wasn't really "the Evangelical candidate" in the sense that Dubya was; he just made common cause with them (against an incumbent who was an actual Evangelical!).
Yeah Reagan wasn't the evangelical candidate, but it was the apogee of Moral Majority and televangelist power so he had to recognize their authority, he was pretty friendly to social conservatism, the astrology aside.
But, yeah, that style of Republican politics is pretty thoroughly discredited now, even though there's still obviously a lane for extreme social conservatism presented differently.
Everything's gone more racial.
