RCP poll had Hillary up by more than ten points in the fall of 2016 so it seems that "real clear politics ain't as clear as they claim. Notice what's missing is a poll about support for Biden
Gee, such an original observation; your must have spent hours researching this conclusion.
Trump is president only because 70.000 votes in Three States gave him enough electoral college votes. trump had no mandate to lead, and his administration will go done in history as The Great SNAFU; no more incompetent, inept and psychologically unfit person has every occupied the White House as he has.
I can be certain that future polls will add one more factor into the algorithms to take into consideration the hate and fear factor which was the determinate factor in trump's rhetoric, which provided him the vote of racists, white nationalists and misogynists.
