Meanwhile, Trump lost support among exactly one demo: white males. Are white males disputing this? Yes - because they didn't cast those votes.

One thing to remember is that info about race isn’t tabulated from voter data itself or anything — it’s only collected via exit polling. So I’m not quite sure what you mean by white males disputing this (because, by definition, they’re the ones who originally reported it).

Of course, we could question whether the exit polling is correct here — though I think the two major exit polls both suggested a drop in white male support.
