Yes I agree, but IMHO one will be toward the light and the other to the dark.
There are somewhat surprising points of agreement between the two that may have something to do with it as well. Unfettered immigration, illegal and legal, during an almost decade-long period of economic difficulty and dislocation is obviously resonating across the board. They both have spoken against illegal immigration and at least hinted that legal immigration has been excessive. Sanders is afraid it will collapse the welfare state, one of the few rational things he believes. Trump views it as an existential threat to the nation itself, not in so many words but it’s there if you look. Also, he believes that it’s the purpose of government to defend the interests of the governed, the citizens. That’s a truism that has fallen to the wayside on both sides of the aisle politically. I’ve never understood what is supposed to be so wrong about being nativist when it comes to one’s own country and one’s own fellow citizens.
