 When my opponent or anybody else says, well, Bernie's a nice guy, but he's thinking too big, making public colleges and universities tuition free. Oh, that is a crazy idea. It is not a crazy idea. We can make it happen. And mock by words, mock by words, if millions of students and young people demand it, it will happen. And then 20 years from now, some guy or woman will be up here. And she'll say, well, you know, 20 years ago, public colleges and universities weren't tuition free because that's crazy. How could that be? That's how change comes about. Have a vision. Be prepared to stand up and fight for what is right.
