The sources I've seen claim most of Trump's support comes from Americans making above median income, but privilege is intersectional, and the forms of privilege you listed don't overlap perfectly. In general, by privileged I meant taking the side of the status quo, IE (mostly) white, cisnormative (supporting exclusively heterosexual marriage and believing only two biologically-derived genders exist,) culturally Christian and conservative, which in the US is always the more politically and culturally defensible position.

Of course, not all of these apply to all Trump supporters (his gain among Latino and Black voters in the last election being a counterexample) but I seriously doubt none apply to any.
