It's like pro basketball. If that was your only source of information for population statistics in the USA you'd imagine that the average person was a 7' tall black man.
Raising your sights to check out the far more numerous audience at an NBA Game you'd realize, instead that the average person was 5' tall, overweight, and needs to get out in the sun everynow and then.
My evidence was not just anecdotal. The official estimate from all supervisors of elections was 138 million. That was late in the game. The total will end up at maybe 122 million or so.
