As president, I will fight to make tuition in public colleges and universities free, as well as substantially lower interest rates on student loans.

I thought the Bush economic policy was a disaster. We lost 500,000 private sector jobs during his tenure.

I think the Democratic Party has got to make fundamental choices.

The focus, to my mind, is to make sure that Donald Trump does not become president of the United States. I think by temperament he is unqualified to be president. I think his views - you have a guy who's running for president who rejects science, doesn't even believe climate change is real, let alone wants to do something about it, wants to give hundreds of billions of dollars in tax breaks to the top two-tenths of one percent.

This is what oligarchy looks like: Today, the top one-tenth of 1 percent owns almost as much wealth as the bottom 90 percent. The top one-hundredth of 1 percent makes more than 40 percent of all campaign contributions. The billionaire class owns the political system and reaps the benefits from it.

We are living at a time where a handful of people have wealth beyond comprehension - huge yachts, jet planes, tens of billions of dollars, more money than they could spend in a thousand lifetimes. But at the same time, millions of people are struggling to feed their families or put a roof over their heads or find the money to go to a doctor.

The Postal Service is a vitally important institution for the American people. It must be saved.
