We are living in the richest country in the history of the world, yet we have the highest rate of childhood poverty of almost any major country and millions of people are struggling to put food on the table. It is my absolute conviction that everyone in this country deserves a minimum standard of living and we've got to go forward in the fight to make that happen.

We live in a country where a small number of people have incredible wealth and power. America has more income and wealth inequality than any other major country.

Do not tell me that I have not shown courage in standing up to the gun people, in voting to ban assault weapons, voting for instant background checks, voting to end the gun show loophole and now in a position to create a consensus in America on gun safety.

What my campaign is about is a political revolution - millions of people standing up and saying, enough is enough. Our government belongs to all of us, and not just the hand full of billionaires.

We have to develop a strong economic message which says every American is entitled to health care through a national health care program. And we're not going to allow these large corporations to push through trade agreements which allow them to throw Americans out on the street and run to China.

Do the elected officials in Washington stand with ordinary Americans - working families, children, the elderly, the poor - or will the extraordinary power of billionaire campaign contributors and Big Money prevail? The American people, by the millions, must send Congress the answer to that question.

Politics is not about a person. We transform America not by electing some guy or woman to be president; we transform this country when millions of people stand up and fight back. That will result in good leadership on top. So the goal right now is not to worry about who's going to be running in 2020 or 2080. The goal now is to mobilize millions of people around a progressive agenda.
