Pete Buttigieg gave a convincing speech at the 2020 Democratic National Convention:
Beau Biden lived a life of service, in office and in uniform. When you put your life on the line for your country—especially this country—you do it not because it’s a country you live in, but because it’s a country you believe in.
I believe in this country because America, uniquely, holds the promise of a place where everyone can belong. We know that for too many and for too long, that promise has gone unrealized. But we also know America has been at its best whenever we make that circle of belonging wider.
He made the case for Biden and Harris:
Every American must now decide. Can America be a place where faith is about healing and not exclusion? Can we become a country that lives up to the truth that Black Lives Matter? Will we handle questions of science and medicine by turning to scientists and doctors? What will we do to make America into a land where no one who works full time can live in poverty?
