to die on this hill
The polls were in the margin of error
I'm not about to go look up the "margin of error" to see exactly how much wrong each poll was against what they claim is close enough in horseshoes and hand grenades..
I'm not going to look it up either, but the point remains, the polls were actually correct as they were measuring the popular vote and not the electoral vote. Hillary won by 2.87 million votes, or roughly 2.2% of the total vote, which is likely within the margin of error of the polls. Its arguable that the polls didn't include enough voters from states won by Trump, except for the one pollster I mentioned earlier.
You forgot one minor detail...
There is a good reason why the Democrat party is so virulently opposed to voter ID laws, and it has nothing to do with protecting minorities, it is all about protecting their thumbs on the scales.
