Good question. It may be that election dynamics have changed, and rallies, events, etc. don’t matter as much any more. And that the polls (all of which predicted a huge red wave) have not yet adjusted their methodology to reflect the new dynamics. It is possible that the old polling methodology is over-stating Republican performance. It is also possible that this phenomenon is not uniform nationwide, but is more pronounced in certain locations. I think a retrospective of the chest-thumping predictions of pollsters is in order.
No kidding.
It does not matter who votes or what they vote for. What matters is who counts the votes.
You use a lot of words to say nothing.
