So the rise of whitey didn't occur in 2008 or 2012 because they just hadn't had enough of Obama's program by that point?
That defies all reason and logic, not to mention the point that the raw numbers simply demonstrate otherwise.
Trump's 2016 vote was actually lower than Romney's 2012 vote even though the population is bigger. Some of Romney's voters didn't vote for Trump. HRC lost the election because the number of Obama's voters who didn't vote for her was far larger than the number of Romney voters who abandoned Trump..
AFAICT from the raw numbers, in order for the Whitey theme being the dominant factor in Trump's EC victory to pan out we'd have to have some indication that the number of Romney voters was almost equal to the number of new white nationalist voters.
Maybe that's what happened, but it seems unlikely.
Not to mention the point that the change in the EC between 2012 and 2016 occurred in some of the battleground states, not everywhere.
Sooner or later the Occam's Razor theory kicks in. WYSIWYG
