As I wrote last month, the shock caused by Trump to many of those on the American Right is the realisation that many of their "base" must be idiots.
More along that line can be read at the above link, which concludes that if Trump really succeeds, it could be the end of the "reasonable" Republicans :
Over at The Federalist, Ben Domenech penned a terrific post the other week, asking “Are Republicans For Freedom Or White Identity Politics?” When I asked him how this might personally impact us, he responded: “Sometimes parties die. Not there yet.”
Maybe not — but it’s probably not too soon to have our exit strategy mapped out. Will we be forced to make a binary choice between belonging to a political philosophy on the Right that is openly nationalistic and xenophobic — or one on the Left that supports (among other evils)
It’s been a trope forever, but we could really have a “stupid” party and an “evil” party on our hands.
