We are so isolated in our own little worlds, in our own little geographies, that it's pretty hard to understand where someone else is coming from. And so I think that we have to really think about what that means as a country and, frankly, whether this segregation that we have is durable over the long run.

As a culture, working-class white Americans like myself had no heroes. We loved the military but had no George S. Patton figure in the modern army. I doubt my neighbours could even name a high-ranking military officer.

We need to think about how we teach working-class children about not just hard skills, like reading and mathematics, but also soft skills, like conflict resolution and financial management.

People in my hometown voted for President Reagan - for many, like my grandpa, he was their first Republican - because he promised that tax cuts would bring higher wages and new jobs. It seemed he was right, so we voted for the next Republican promising tax cuts and job creation, George W. Bush. He wasn't right.

When I decide who to vote for as president, I ask myself who will be best for America and for the world. An important component of my answer involves my assessment of the candidate's willingness and ability to protect Israel's security, since I strongly believe that a strong Israel serves the interests of the United States and of world peace.

The role of social media is critical because it helps to spread cognitive dissonance by connecting thought leaders and activists to ordinary citizens rapidly expanding the network of people who become willing to take action.

Everything about my politics has been about the future.

Political civility is not about being polite to each other. It's about reclaiming the power of 'We the People' to come together, debate the common good and call American democracy back to its highest values amid our differences.
