“No, not all Trump sup­port­ers are ra­cist. But vir­tual­ly all ra­cists, it seems, are Trump sup­port­ers. And all Trump sup­port­ers im­pli­cit­ly con­do­ne his bla­tant pre­ju­di­ce. At the very least they don’t con­sider ra­cism to be a re­ason to turn against the pre­si­dent. For a dis­tur­bin­gly lar­ge num­ber of Trump vo­ters, it is the pri­ma­ry re­ason to sup­port him.”
