I'd just like to say US pollsters can't poll for sh*t. German exit polls are usually incredibly accurate. How does Trump up by 5-7 turn into him losing by 4?
Pollsters cheat off other pollsters and throw away polls that are against conventional wisdom.
Example: 2014 Virginia Senate race
Nearly all pollsters had Sen. Mark Warner leading by double digits. A couple of days before the election, a poll was done showing a tied race. The pollster threw the poll out because he didn't believe it.
Warner won by about 0.6%.
