On Sunday, at the Corinthian Baptist Church in Des Moines, former President Bill Clinton, looking frail and sounding faint, stumped for his wife, working through her qualifications with a husband’s devotion and a Svengali’s facility.

But one thing he said stood out to me for its clear rhetorical framing.

He attributed much of the anger that’s present in the electorate to anxiety over a changing demographic profile of the country, but then said: We are going to share the future. The only question is: What will be the terms of the sharing?

This idea of negotiating the terms of sharing the future is an expansive one, on both ends of the ideological spectrum, but it also seems to me to be an internal debate white America is having with itself.

Much of the energy on both the left and the right this cycle is coming from white Americans who are rejecting the direction of America and its institutions. There is a profound disappointment. On one hand, it’s about fear of dislocation of supremacy, and the surrendering of power and the security it provides. On the other hand, it’s about disillusionment that the game is rigged and the turf is tilted. It is about defining who created this country’s bounty and who has most benefited from it.
