Interestingly enough, Bannon seems to understand our current era; but he's dead wrong about his position (along with President Trump's) in it.
He thinks that the "gray champion" that Neil Howe and William Strauss wrote about in their book, The Fourth Turning, is Donald Trump. The gray champion is basically the political leader who unites the American people and guides us through the fourth turning along with the inevitable secular crisis that occurs during it. The 3 gray champions in American history were Washington, Lincoln, and FDR.
There's two things Neil Howe has stated that will indicate whether Trump is the gray champion: he must not only win reelection by either a decisive victory or a landslide, but he must be propelled strongly by the youth. Lincoln won against the former commander of all Union soldiers, General George B. McClellan, in 1864 because the young Union soldiers ultimately broke very strongly for Lincoln (75.8%-22.9%). In 1936, FDR won reelection with somewhere around 85% of the under 30 demographic going for him.
Could Trump simultaneously win reelection solidly and boast strong support among millennials? I highly doubt it. And that's why I think Bannon has miscalculated greatly with Trump being the supposed "gray champion" who will lead America through the fourth turning.
Where did you get that info come from? I really would like to find those numbers.
