My earliest memory campaigning was going to the dump to get petition signatures or handing out literature.

Where I grew up in Vermont, there is no municipal garbage removal. You have to bring your trash to the dump every weekend. Something like three hours on Saturday morning, the entire town goes in. It is actually a very efficient place to do politics. I would go to the garbage dump, get petitions signed, give out literature, talk to voters.

Bill de Blasio is a very good friend. I remember bringing up a whole caravan of cars to help volunteer on his Public Advocate race.

90 percent of the cost of malaria drugs has come down because of the work of the Clinton Foundation. There are over 10 million people around the globe today receiving life-saving HIV and AIDS drug treatments because of the Clinton Foundation.

We look at Donald Trump: his bottom line is interconnected to all kinds of financial interests that he refuses to disclose. They actually affect his net worth.

But picketing - picketing for or against something, and handing out literature - these are conspicuously formal actions. They have to be understood as indirect communication.
