So....
Clinton led by 4 on 10/29, trailed by 2 on election day per IBD and subsequently lost.
So be careful.....
(a) Yes, their final "-2" was wrong. She finished roughly +3% in popular vote, which is what polls are estimating. She lost, but the IBD/TIPP poll was 5% wrong.
(b) If there were such a 6% shift this year, equally across the country, Biden wins.
(c) Note that in 2016, Trump on Oct. 29th had 41% of the vote. He got all the way up to 45% of the vote. Clinton had 45% and dropped to 43%. Biden is over 50% and would drop to 49.6% in the four-way.
(d) Roughly 14% were voting for others or unsure on the 29th. By election day, that had shrunk, with much of it shifting to Trump at the end. This year, the numbers are 10% lower, at roughly 4% - and they are breaking for Biden.
So, sure. "be careful," as if what I do to be or not be careful makes a shred of difference.
But you might try getting your faux-analytical head out of your Trump-stained ass.
I know the election is not in the bag. But I know that it will take more than a Comey letter and some misogyny to change this election's likely result.
