Whether the population is one million or one hundred billion, all you need are 10,000 representative members to get +/-1% accuracy on who they will vote for.
but AI guessing the outcome in light of those few as you say is still incorrect overall tallying.
seriously depending what 10,000 “representative” members can be swayed by things.
they just want people to believe they are insignificant and God says that isn’t true so AI and those who think it’s so great are wrong.
