Just a reminder that NYT/Siena had North Carolina clinton+8 in late October 2016, Trump won it by 3-4 points.
Well, the last NC Siena Hillary/Trump poll was a tie (with heavy undecideds in Trump leaning demographic groups), so its interesting that you would choose to bring up the... second to last one.
The other last-minute state poll I remember them doing was Florida, in which they showed Trump doing actually a couple points better than he ended up. So, two misses by 2-3 points, but in opposite directions. No pollster is perfect, but the way people here try to grasp at straws to discredit even the better ones is really something.
Also, Siena was basically the best pollster in 2018, along with Emerson (I don't trust post-2018 MTurk-era Emerson, which uses a completely different methodology though). Siena wasn't perfect in the midterms but they were very good and didn't really have any overall partisan bias.
