Each didn’t win the popular “vote”. The obvious widespread cheating was the difference.
Hillary won the popular vote in '16. The Left was overconfident. After all, everyone they knew were going to vote in Hillary. They were stuck in their bubble. So they were caught off guard by Trump's surprise victory.
'20 was a different story. But most likely, thousands of mail in ballots made the difference in the battleground states.
Not as many as you would think. But if you print a couple of thousand extra votes in a critical state, that's enough to decide the election.
I loathe this argument. I care about who is sworn in on Inauguration Day. Period!
