The polls average was totally wrong the whole of 2016. If 90% of the polls are skewed suppression, biased polls, the average is skewed, suppression, biased polls too. That is basic math.
In 2016, it was only in the last few days that the fake news fakers tightened their polls to make it look like they had it close all along. They didn't. For all of 2016, they were calling it for Hilary to win by up to a massive 15% as late as October 18.
Both the Washington Post and Time magazine had Hilary winning by 12 and 14 percentage with just two weeks and 12 days to go to the elections.
You (and your defenders, Thing 1 & Thing 2), obviously don't understand the difference between a polls average and your standard laughable tactic of idiotically cherry-picking a couple of individual polls on one specific date (as you just moronically did again).
And you're laughably trying to lecture someone else about "basic math." Chuckle
