I did have a theory that increased polarization may have led to increased value of early general election polls. Once polls came out that started showing Utah being more likely to vote Democratic than Minnesota, and other similarly ridiculous things, I was clearly wrong.
That said, even back then I didn't believe the polls. I just thought they may not be
totally useless. Big difference. If you're so inclined Morden, you can dig through my posts from 2014 about how I predicted Hillary would win by 5-6 points even when she was leading by 20+.
