The case to be made is that we have got to get people involved - continue to get people involved in the political process at every level.

Things are getting worse. You know, when you look at this campaign, and you realize the enormously serious issues this country faces, right, we got a collapsing middle class. We have more wealth and income inequality today than we've had since the 1920s. We have all of these enormous issues.

A number of years ago, people were saying normal relationship with Cuba, what a bad and silly idea. They're Communists, they are our enemy. Well guess what? Change has come.

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.

As a result of the Citizens United Supreme Court decision, American democracy is being undermined by the ability of the Koch brothers and other billionaire families. These wealthy contributors can literally buy politicians and elections by spending hundreds of millions of dollars in support of the candidates of their choice. We need to overturn Citizens United and move toward public funding of elections so that all candidates can run for office without being beholden to the wealthy and powerful.

The middle class is collapsing and we are moving toward an oligarchic form of society, where the billionaires will control the economy and the political life of the country.

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.
