An Overdetermined Problem Published by digby on February 20, 2024 From the man who runs 538 since Nate Silver left: Another note on the polls: There is an abnormally high level of non-sampling error in polls right now. In Summer/Fall POTUS campaigns we normally see non-sampling error of around 1.5%—implying a total MOE of around 6% for the average poll. But extra error is about 2.5% today. 1/2— G Elliott Morris (@gelliottmorris) February 20, 2024 Notably, accounting for this extra error does not meaningfully change the state of play — Trump has a slight ~2pt lead — but it *does* significantly decrease the confidence we have in his lead.
