Two polls I read about that were accurate:
1. I followed the LA Times poll. They tracked a number of voters week after week for responses and were the most accurate of the bunch.
2. Another poll that nailed it got around the bias (not wanting to tell a stranger Trump was their pick) by asking “Who are your family members or neighbors supporting?” That poll was also extremely accurate.
Dornsife/IBD-TPP/PPD were online polls and all were accurate.
That’s where the future of polling is at.
Every one else ignored, dismissed and overlooked the Trump trend.
You could see it on the Internet.
