Neither of the current major party candidates is the "Grey Champion".

[Einzige]

I still bet that, even if as you say the next decade is our equivalent of the 1940s or 1860s, no singular Grey Champion emerge. It'll probably be more of a collective endeavor this go-around, emerging out of trends Obama started in this decade. I think you can have a momentous last half of a Fourth Turning without necessarily having a transcendent Gray Champion in charge at that time.
