Believing statements like that put Trump in office in 2016.
I would encourage people to ignore polls right now. We are a year away from the election. We don't have a democratic candidate or platform yet. Trump, while pissing people off daily still has his followers.
My prediction is this: He wins again after losing by a larger margin of the popular vote but winning the electoral college. This will cause a total meltdown amongst democrats and we will see a new war cry (no pun intended) from Warren and "IMPEACH 46" will be the new chant.
Trump hasn't lost ground among his supporters.
