Income and wealth inequality have reached obscene levels, the threat of climate change is more frightening than ever, and the billionaire class is now allowed to spend unlimited amounts of money to buy the candidate they want. And it is up to us to stand up and fight back. If we stand together, there is no limit to what we can accomplish.

The decision is I'm going to do everything I can to fight for the working class of this country, the low-income people against income and wealth inequality, do everything we can about climate change.

Clearly we must do everything we can to protect our country from the serious potential of another terrorist attack, but we can and must do so in a way that also protects the constitutional rights of the American people and maintains our free society. We can do that without living in an Orwellian world where the government and private corporations know every telephone call that we make, every website we visit, everyplace we go.

What I do believe absolutely is that in the middle of a recession, the American middle class and working class needs a tax relief.

I believe, along with Pope Francis and almost all scientists, that climate change is threatening this planet in horrendous ways, and that we have to be aggressive in transforming our energy system away from fossil fuel and defeat the Keystone Pipeline.

Politics is not a baseball game with winners or losers. What politics is about is whether we protect the needs of millions of people in this country who are hurting.

We have to enforce the individual mandate. We're losing a lot of money that is not coming into the system.
