Let's just clarify some things here:

Only 8% of the American population support abortion bans that the majority of the US states would enact if Roe V. Wade is overturned. (1) (2)

The question isn't binary. 8% believe that abortions should be totally banned in all cases, while 19% think they should be totally legal in all cases. That's more than double.

But this only accounts for 27% of Americans. What about the rest.

The largest group is the 42% of Americans who believe abortion should be legal in most cases. The second-largest group is the 29% of Americans who believe abortion should be illegal in most cases, but with exceptions. The vast majority of these states who will pass bans will be going against this 27%, as they have no exemptions for rape or incest or even to save the life of the mother.

Adding these numbers up into a binary, you come up with 61% in favor of abortion and 37% against it.

Here's where it gets trickier.

The Senate that nominated the Supreme Court justices who made the decision only represent 17% of the American population. This is because of Senate disproportionality that prioritizes rural voters over urban ones. Someone who lives in Wyoming gets sixty-six times the vote as someone who lives in California. It's literally as if people in Wyoming got sixty-six ballots for the Senate elections and were able to fill out all sixty-six and they would be counted, while someone in California just got one ballot.

Donald Trump lost the popular vote to Hillary Clinton by 3 million votes.

The Senate, the former President, and the Supreme Court (whose justices were nominated by the Senate and the President), were all elected by a minority of the American population. In the case of the Senate and Supreme Court, less than 20% of Americans elected the people who catalyzed these decisions.

This is the legitimacy crisis we face. We can't have a functioning democratic republic that represents less than 20% of us.
