This is a very sad statement.
Everything, and I mean everything, that is done by man is done with some modicum of self-interest. From love of family, wife, god...you name it, there's a selfish reason/purpose/goal at the base...even martyrdom is selfish. It's the way of the world.
If pointing out that something is harming us, slowly yet surely, like a silent cancer grows, isn't that a good thing?
If someone takes a further step on marshalling efforts to battle this harmful phenomenon, isn't that also a good thing?
I guess I don't see the downside that you do. Sure, political leaders can go too far in reaching their goals but that's why we have a constitutional system of checks and balances to ensure that lunacy does not follow. Sure that system has failed us for the moment with Bush, but it is catching up.
As for Hillary Clinton--I couldn't hear the YouTube movie--she, as a politician, is answerable to the will of the people.
It is the Oil Industry, which greases the political skids in a manner you or I could not, that is answerable to no one but its own interests.
