Basically, he's talking about rerouting the water coming from the Rockies that go into the Pacific and moving it into the drought ridden bits of California.... I think.
He's doing this with the phrasing you'd use to explain how the water cycle works to a toddler, mind you. So, if that's how he's trying to explain it to adults, that would suggest it's the only way he can understand it.
Okay, you say "phrasing," but what he said is there is a giant faucet. Given the other retarded shit he has said, how do we know he doesn't literally mean a physical object that turns?
