Um, you weren't in California in the mid-90's were you?
Google "SOS--save our state"--Rep Governor Pete Wilson's campaign for reelection in 1994. Nor was the sort of Latino-bashing that so sickened me in that campaign a new thing to my jaundinced California resident since 1983 eyes. Generic bile against Latinos was just part of the white conservative package in California as I knew it, as ubiquitous as separate drinking fountains in the Jim Crow South. English-only initiatives and so forth...my favorite response to that was the cartoon of "California grinds to a halt as millions struggle to think up the English word for 'taco!'" This was the 1980s. And it takes just a glance at California history to trace this back, well, to the Bear Flag Revolt and earlier actually.
Reagan looks "liberal" mainly because he was busy laying the groundwork for Bush the Elder, who took us farther right, to enable Bush Jr to take us much farther right, whom Trump owes for opening the way. It is all one big shared project and I hold the lot of them equally accountable.
