Wrong. Most pollsters had it right in 2016. They had Hillary by about 3%.
I dont know if you are just repeating a Dem talking point out of ignorance or being purposefully provocative, but thats flat out wrong. They did NOT have Hillary by 3%.
Right before the election her chances of WINNING (not getting the popular vote) was at 98% in many media outlets.

Yeah, they nailed it, within 1 point because Hillary won the popular vote by 2.1. And that is why "the polls had it wrong" is BS. The polls had it right. But....The analysis of the polls was wrong because of the Electoral College.
