This needs to be pinned at the top of every polling board going forward.
Even if it is it won't matter. Quite a few hacks insisted that the charts going back every election for over a decade meant nothing because reasons and surely this time the Nevada polls wouldn't overestimate Republicans! I fully expect an encore in 2020. The ride never ends.
The Venn Diagram of people who were insistent that Dean Heller would win and those saying that Trump will win Nevada because of some poll will be a circle.
