I think you’re making an academic rather than practical point. Sure, he won a much larger share of the electoral college than the popular vote and the existence of the electoral college likely influences some voting patterns. Even then though, in PA he won with barely 1.5% more of the vote yet got all 19 electoral votes. Given the how close the election was forecast and how important PA was, I don’t think the electoral college drove much of the voting patterns. So my point still stands: he barely has a mandate and most certainly did not win an overwhelming victory. And yet, he gets to implement a radically destructive gutting of the federal government.
