Barack Obama: “He has warned that competition over resources could lead to conflict and population movements.”

If I had a blame pie for why politics is so polarised and why we're seeing a rise of populism in many places, it's because of that information that is going into our brains every day.

I think when we act on that basis, it doesn't always work out, but over time things do get better.

It is a decision about how do we face and embrace this finite amount of time we have on the planet.

Looking forward to being in Detroit on 10/24 to campaign for Jocelyn Benson, Abdul El-Sayed and Democrats up and down the ballot in Michigan.
