When you're in governance, you understand the limitations and the complexities of governance.

If we got rid of everybody in Washington who sold access for donations, then the town would be empty. But it's unseemly.

The zooming wealth of the top 1 percent is a problem, but it's not nearly as big a problem as the tens of millions of Americans who have dropped out of high school or college. It's not nearly as big a problem as the 40 percent of children who are born out of wedlock. It's not nearly as big a problem as the nation's stagnant human capital, its stagnant social mobility and the disorganized social fabric for the bottom 50 percent.

I want to limit the effects of the power of donors, no question about it.

[Betsy DeVos] is quite a smart person, capable, pretty sophisticated in subtle thought. And so to me, that puts her in the realm of policy. But we're in a climate where, as today, she tries to visit a school, and she can't even do that because protesters are blocking that.

I think there are two basic approaches you can use for campaign finance. One is complete openness, everybody knows absolutely everything, but no limits. But you let people decide.The other is just have a national public system.

The more attention Hillary Clinton gives to the country, the less people seem to like her.
