How the specific electoral system works is irrelevant. In our case, our electoral system is designed to make most voters' votes not actually matter, so I really don't care about it one bit when talking about who had more or less support in the country as a whole. Trump only got 1.5% more votes than Harris did. That's not a blowout.

Even if you insist on going by electoral votes, 58% to 42% isn't a blowout either.
