The polls were much better this time. They pretty much all had it as a toss up and it was.
They were a little bit better, but they were not good. The main problem still remains. They all miss to the left. They missed by less this time, but they still missed to the left. Just like they do 90% of the time. And just like the left does with everything, they crap on anything perceived as leaning right. Rasmussen, Trafalgar, and other pollsters on the right did the best again. But 538, NYT, etc. Just throw them out and call them partisan hacks. The only difference is they may miss to the right instead of the left, but they generally miss by less. Plus, they are the main reason the polls missed by less this year. They pulled the RCP averages to the correct side.
538 aggregates/projections missed to the left on every swing state called. Georgia by 1.1, NC by 2.3, PA by 2.4, WI by 2, MN by 1.3, OH by 3, FL by 7.1, VA by 1.6.
RCP was marginally better because they don't simply throw out or ignore right leaning pollsters. They missed to the left on GA by 0.9, NC by 2.2, PA by 1.9, WI by 1.3, OH by 2.6, and FL by 5.2. They missed to the right on MN by 0.4 and VA by 0.2.
We don't know on NV, MI, or AZ yet, but they are all trending to miss to the left.
The main take away is that the polls are still biased en masse, but a little less biased than in years past. It just comes down to them not wanting to see the truth if it doesn't match what they want to see.
I know Nate Silver and his minions want to pitch this as "the polls were right, it was a toss up", but that's really not true. Everyone that works there wanted a different result. They make no bones about it. They view everything through a blue lens and explain away or ignore things that don't fit their narrative. I've been following this and doing data analysis for a month at this point. The signs were there. Trump was the favorite, and it really wasn't going to be that close. It was there to see. My personal projection was Trump with 306 or 312. I destroyed 538, and it wasn't hard.
Oh, and the Senate polls were pretty much garbage. So, no, the polls weren't right.
