Skew the polls so crazily that no one will be able to take them seriously.

Thing is, no one takes them seriously NOW.
I mean - look at 2016. How much more of an abject failure could the polls have BEEN? And yet, on that very night, many of the pollsters were making excuses, and right after we went right back to where the media wanted us to be - following the polls.
Up until about 11:00 on election night, they were still certain Hillary had it in the bag.
The smugness was sweet to see washed off their faces in the early hours of the new day.
