> 16 point misses by seasoned pollsters are not accidental.
Not a pollster, but Nate Silver publicly challenged someone on Twitter to a $100k bet over how red Florida would go. IIRC Silver was predicting 3-5% margin, Twitterer said minimum 8%. Trump won by 14%. Even Silver, who lived and breathed analyzing polls and their reliability, made a mistake of that magnitude with his own money on the line. Sometimes the votes don't line up with polling, and sometimes the professionals genuinely don't see it coming.
