Isn't insisting that Trump is not a legitimate president because he didn't win the popular vote even worse?
Worse than what? What is your criteria for determining worseness
For four years, anti-Trumpers screamed the electoral system is a fraud, phoney, not fair, and makes Trump an illegitimate president. I don't recall concern how those complaints undermine the American system of government and constitution?
Good lord. What sweeping generalizations. You don't help your arguments by constantly employing them. It just makes you sound nuts.
I don't remember anybody screaming that stuff. Seems like there was a some rational discussion of eliminating the electoral college and moving to popular vote, but most people realized that it was so difficult to amend the constitution we were stuck with it so the discussion just faded away.
