I remember going to a Trump rally in South Carolina, and it was really important and it was really interesting to talk to the people who'd shown up there because they were not caricatures, and so often Trump voters, Trump supporters were being portrayed in the media, probably I'm guilty of it as well, as caricatures. Each of these people, and I talked to maybe a dozen of them, had a very particular reason why he or she was supporting Donald Trump , but these were not casual, inexplicable decisions.

But fairness is where we’re heading, at least in regard to marriage, which has emerged as the terrain on which Americans are hashing out their feelings about gays and lesbians. The trajectory is undeniable. The trend line is clear. And the choice before the justices is whether to be handmaidens to history, or whether to sit it out.

Another way in which our system is unfair. Why do Iowans get so much of a bigger voice every four years than everybody else? Ditto for New Hampshire. There are proposals and it could well happen that we could have a rotating calendar where different years different states went first. I would endorse that.

I think with Donald Trump we're seeing the sort of utterly vanished line at long last of enter - between entertainment and politics. I mean there's always been an enormous dose of entertainment in politics. Trump has completely erased that line but the Trump phenomenon when it comes to where the media's culpability is how much we should be beating ourselves up, that's a complicated question because one of the distinctive features of our era is we know exactly what consumers are doing almost in real time.

If you look at why do we end up with the nominees that we get often? It's because you have only a very small number of Americans participating in the primaries, and those people tend to be your most dyed in the wool partisans.

You don't feel you have the same voice in a presidential election if you live in a solid blue or a solid red state. I also don't think we've educated voters well on the different ways in which primaries work in different states. It doesn't need to be the case that you end up with one Democrat and one Republican, you have open primaries, you can have jungle primaries. There are various permutations and combinations of how to do this.

Campaigns waged with lies presage governments racked by distrust. The sclerosis starts there.
