We have to figure out ways to scare and entice our leaders more effectively than the fossil fuel industry has managed to scare and entice them. They've got the big checkbooks. We've got to have the big crowd.

Here, there's more of a movement, it doesn't mean we're winning any more, but we're at least fighting.
