It used to be that the working class, broadly speaking - Americans who worked with their hands, who worked in factories, who were not in management - were an interest group, a political interest group. And their main spokespersons were the Democrats. Their platform was the Democratic Party. And that began to change after the 1960s. Not for black or other working class Americans, but for white working class.

Ideology knows the answer before the question has been asked. Principles are something different: a set of values that have to be adapted to circumstances but not compromised away.

American politics can produce great men and women, but it is profoundly insular.

People in Congress are willing to shut down the entire government or to make it impossible for a Supreme Court nominee to get a hearing or for routine appointments in the executive branch to go unfilled for years because of a hold placed by a senator.

The way Donald Trump talks about the problems of black Americans as a kind of separate group who are not part of his audience but he's kind of reaching over his audience or behind his audience to black Americans, saying what have you got to lose? As in you might as well join me because the Democrats haven't done anything for you. But joining me means joining this group that already supports me.

Character is destiny, and politicians usually get the scandals they deserve, with a sense of inevitability about them.

We all know who Donald Trump's talking to.
