People don't know where they stand and what they're going to lose, and that makes things uncertain. The political parties try to meld people together, but then that becomes a problem. There are parallels here, to American cities, which, in the '80s, with massive rural to urban migration, saw incredible amounts of violence.

I belong to a bowling team with black and Latino coworkers. And when we get together and we talk about politics - I'm almost quoting him - he said, we don't talk about Black Lives Matters. We talk about what matters to our families. We talk about jobs, and we talk about the fate of the country. That is America, and you can reach those people.

I would say that the one incredible thing that Karachi has going for it is the unabated supply of new migrants that pour into it day after day. It could be a poor factory worker who simply wants a job, it could be an ambitious guy coming for an education - they all add hope and vibrancy to the city. Now, this is not something that is generally taken as positive in Karachi. But the hope is that the migration that comes into the city replenishes its stores of resilience and energy.

I prefer a dirty victory to a noble defeat.

Republicans are now trying to stop Donald Trump. And there was much more ferocious and widespread criticism from Republicans of Trump this time around.

You do have this circumstance in Karachi that because people know things are changing, the stakes are higher. Everyone is thinking, "My home is threatened, my job is threatened, my identity is threatened, my world is threatened." And that creates a very particular sort of climate, that is linked.

The president who did the most for black Americans in 20th century history was Lyndon Johnson, and he got his hands dirty by dealing with Southern senators, Southern congressmen, horse trading with them, cajoling them, learning what not to talk about. And he got civil rights passed and Great Society programs. That should be the model. Get over yourself.
