Funny how that term caught on, isn't it? I tell everyone, I hated it. Somebody said 'drain the swamp' and I said, 'Oh, that is so hokey. That is so terrible.' I said, all right, I'll try it. So like a month ago I said 'drain the swamp' and the place went crazy. And I said 'Whoa, what's this?' Then I said it again. And then I start saying it like I meant it, right? And then I started to love it, and the place loved it. Drain the swamp. It's true. It's true. Drain the swamp.
