When Donald Trump yells at his supporters to throw somebody out of the hall - and usually that somebody is brown or black or often is - that means he's galvanizing a kind of mob spirit, which is also a racial mob spirit.

Gingrich was a far more volatile and aggressive individual than Boehner, but the institutional norms of self-restraint, and perhaps even self-interest, have broken down under the pressure of an increasingly abnormal Republican Party.

The biggest issue for me is whether large numbers of Americans can begin to think that government can actually help make the country a fairer place. And that's partly a matter of policies that achieve results in terms of reducing inequality and raising middle-class and working-class incomes, which have been flat for decades. But it's also symbolic and rhetorical, it's whether Hillary Clinton can - or whoever's president - can persuade Americans that it's happening and that they can begin to trust their elected officials a little bit more and their institutions of government a little bit more.

We focus on that really repulsive minority of racists. But then there's a continuum that goes all the way to, you know, what used to be called the white backlash or to, you know, the feelings of some white people that they're losing out and that the jobs and power and sort of the culture is drifting away from them and toward people who don't look like them, who don't - who they don't know very well. And that's not necessarily - I don't equate that with the hardcore ideological hatred of self-identified racists.

One book that I heard was circulating the Green Zone was "Bureaucracy Does Its Thing" by Robert Komer , who worked for President [Lindon] Johnson in Saigon. This book is about the inevitably of screwing up when a country takes on a war with so little understanding of the country they are fighting.
