You need to show papers to go grocery shopping: that's OK. You need to show papers to vote: that's not OK.
Do you see the inconsistency?
Biden is the most popular president ever, millions of votes more than Obama.
It comes down to a few ten thousands (or less) in critical swing states.
There's a compelling statistical argument to be made that states like Georgia, or maybe perhaps even bigger margin in FL, might have gone another way without laws & regulations to make it harder to vote and cast a ballot by mail.
My point wasn't about "who won", only pointing out the statistics of popularity, considering that an election is basically a popularity contest.
The most unpopular president (and vice-president) got more historical more votes than the last most popular president of the past 50-100 years.
