The polls weren't wrong, it was the interpretation of them that was wrong. Hillary won the popular vote by a small margin as indicated by the polls, they accurately identified the battleground States and it was pretty much the States that were indicated as being closest that Trump flipped. The result was also within the margin of error.
The part that was wrong was observation error. If you for example film a worker who knows you're observing them do a process, they won't make as many mistakes because they know you're watching them. Your observing the process changes the results.
In this case, the anti-Trump leftist demagoguery did cause observation error in exit polls. A small percentage of people didn't want to get into admitting they are voting for Trump and potentially get into it with a hate filled leftist moonbat. It was enough in the closest States to make the difference. The media did not account for how their vitriol to Trump could effect the answers they got at the polls
I understand what ur getting at but, this is where I see it differently.
They can't be responsible for misinterpreting expected votes,
cuz people lied about who they were actually voting for.
What everyone in the media, her campaign team, and even,
some posters here, got wrong and took for granted,
was the Latino, African American and female voters
they actually expected, would come out in droves to vote for her.
What the talking heads, media, Hillary, the Democrats,
the Republicans, were blindsided by and didn't see coming
because they haven't been seen or heard from...
was the droves of white, pissed off, had enough, voters,
that didn't voted in the last election or haven't been voting!
They all should have been able to see what was brewing,
when Trump walked away with the nomination in the primaries!
