Yeah...people seem to think Trump is a Republican anomaly, but the only thing that is anomalous about him is his greater willingness to break the social compact. Republicans (as a party, not necessarily every single individual person) have been playing on racism and sexism to win elections since Nixon. Ronald Reagan's team, which became the elder Bush's team, which partly became and partly molded the younger Bush's team, made extensive use of dog whistles to scare white voters and signal to them that poor black people (and immigrants) were coming for their middle class prosperity and Democrats were just going to let them, but Republicans would protect them. In that sense, Trump isn't remotely an outlier or anything new as a Republican. He just correctly judged the moment and understood that a populist "tell it like it is" (i.e. being rude, insulting and, most of all, explicitly racist and sexist) campaign would make best use of the standard Republican playbook. Or he may have just gotten lucky and happened to run that sort of campaign at the perfect moment for it. Either way, he's not a break from the modern line of Republicans in beliefs and policy--just in style.
