Which is Not Even Wrong, for it implies the unknowable counterfactual that if Trump had been running a campaign for the popular vote, he wouldn't have won that. E.g. lots of people don't bother to vote when they're in "enemy territory" and they know their vote won't count for anything.

You can't take a situation based on X strategy, and then change the rules to Y strategy after the game has been played by X, and make anything more of it than a silly rhetorical point.
