I want to know in this day and age, whether it is possible for any candidate who is not a billionaire or who is not beholden to the billionaire class, to be able to run successful campaigns.

You know, let me be very clear. I supported Barack Obama originally.

When we are fighting for huge stakes - we're fighting for the future - future of the planet in terms of climate change. We're fighting for the future of American democracy.

There are three major political organizations in this country: the Republican Party, the Democratic Party and the Koch Brothers Party. With billions to spend on campaigns. think tanks and 'educational' organizations, the Koch brothers are the most powerful. We must overturn Citizens United, move to public funding of elections and pass real tax reform.

We need to take a hard look at the war on drugs and the number of non-violent offenders who end up getting their lives destroyed by going to prison. We need to look at mandatory minimum sentencing and give judges more flexibility when there are issues of drug abuse or addiction.

I would love it if everybody in America agreed with me on every issue. I can't get my wife to agree with me on every issue, let alone the American people. It's called democracy. That's what it's about.

Debating, doubting, or rejecting the basic scientific facts about climate change in the face of the overwhelming evidence and overwhelming scientific opinion will not change those facts.
