Agreed! One of our biggest mistakes in 2016 was believing in the outcome of the race to the White House from the comfort of our liberal echo chamber
That said, we didn't really know about Cambridge Analytic yet, or Facebook's complicity in allowing that organization to hack group think on social media, then supported by Fox. We weren't really aware of Russia's efforts to hack our electoral process. And we didn't understand the extent of the GOP's efforts to suppress the vote in key areas.
So even while Fox pundits agree that Biden is in the lead, there's no telling what lengths this particular megalomanic and his sycophantic minions will go to to cheat and steal this election.
As you so eloquently state: If we've learned anything from 2016, it's to expect the unexpected. And no poll from any source is going to give us any heads up as to the rainstorm of cheating and lying and deception and outright illegality we're likely to experience from this unworthy administration from now until November.
