The Affordable Care Act has clearly, as Secretary Clinton made the point, done a lot of good things, but, what it has not done is dealt with the fact we have 29 million people today who have zero health insurance, we have even more who are underinsured with large deductibles and copayments and prescription drug prices are off the wall.

We have to transform our energy system.

Most Republicans are not prepared to stand up to the fossil fuel industry because they get a lot of their campaign funds from the Koch brothers and other people in the fossil fuel industry. That tells me why we have to reform our campaign finance system.

They talk about class warfare -- the fact of the matter is there has been class warfare for the last thirty years. It's a handful of billionaires taking on the entire middle-class and working-class of this country. And the result is you now have in America the most unequal distribution of wealth and income of any major country on Earth and the worst inequality in America since 1928. How could anybody defend the top 400 richest people in this country owning more wealth than the bottom half of America, 150 million people?

I believe the Democratic Party has got to be firmly on the side of working families, taking on the big money interests, who today, to a very significant degree, control our economic and political life.

What I do know is that drones are a modern weapon. When used effectively, when taking out ISIS or terrorist leaders, that's pretty impressive. When bombing wedding parties of innocent people and killing dozens of them, that is, needless to say, not effective and enormously counterproductive. So whatever the mechanism, whoever is in control of that policy, it has to be refined so that we are killing the people we want to kill and not innocent collateral damage.

It's very easy to make fun of George W.Bush, but that ain't going to do it. What we have to do is knock on doors and go into communities where there are people who disagree with us on certain issues.And we have to talk to them. They're our friends. They're our allies. They're our co-workers. We can't see them as enemies.
