Please remember that most polls measured the national Popular Vote.
Clinton will beat Trump in the national Popular Vote by close to 1.8 million votes.
Percentage wise, Clinton will beat Trump by close to 1.5% in the national Popular Vote.
There were 24 national polls released on Monday and Tuesday of election week.
Four polls showed Trump winning. But, only one of those polls was within the margin of error.
Twenty polls showed Clinton winning. But, 15 of those polls were within the margin of error.
Yep, the LA Times wound up being off 4.5% off in Trumps favor.
Perhaps a better method going forward for pollsters would be to adopt a semi national poll. Exclude any state that went 20+ points for one party over the other as outliers. Would be interesting if a polling firm went back and reworked their final poll to see if doing so would have predicted the EC winner.
