A white man stood on the stage - a man known to be a sociopath, pathological liar, and sinking under the weight of dementia - and babbled out whatever he felt like.

A Black woman stood on a stage - a woman known to be intelligent, competent, and a chance for a diverse nation to be represented by a diverse person - and America voted for the man.

There are various reasons why that happened, but I can't make a good argument against your conclusion.
