Again, millions of non-whites voted for Trump.
If you want to argue that Trump wouldn’t have won without the votes of white racists, fine. You argue that white racism is the only reason he won, though, as though there weren’t other factors.
Trump is, IMO, the worst presidential candidate of my lifetime. Biden was a very close second before bowing out before the second election. While I don’t think Harris was that bad of a candidate, I also don’t think she was at all a good candidate. It’s only in comparison to her opponent that she looks good.
