So a right without a Buckley will probably be smaller, and uglier to boot. I would expect this alt-right to be a lot more vigorously opposed to the civil rights movement than OTL's. It will also be much less relevant, and probably not snag a certain Californian actor. I predict, then, that America, on the whole, looks a bit more like a Western European social democracy, but with a right wing that looks (hmm...thinking...) well, looks almost fascist.
