A distinction without a difference. It amounts to the same thing in this case.
"A majority of voters voted against Trump"
"More voters voted against Trump than for Trump"
It doesn't matter because you can make those same two statements about Harris or any other candidate.
You can say "50.1% of the country voted against Trump"...but ~51% voted against Harris.
And then there is the 90 million or so that just couldn't give a fuck.
