Because they're just like women buying a present. Now before everyone gets their panties in a bunch, let me explain. When a woman, whether your wife, girlfriend, whoever, asks you what you would like for Christmas and you say "I'd like a telescoping miter saw so I can finish that project I've been working on", she'll inevitably get you a new electric razor.
Why?
Because even though they know what you want, they decide to buy you what they think you should want. You know it's true, lol. Just like Nancy Pelosi. She actually stated that it was her calling to use her position to save the world. Huh? Did the people of SF vote for here to save the world? (Ok, maybe the whackos in SF did, but you get the point) Like you said, I thought their job was to fulfill the will of the people, not to educate us dumb peasants on what we should want.
Just think when we get 4+ years of the Senate, Congress, and the Presidency telling us ignorant sods what's good for us. Work hard, bust ***, then give it all to those too lazy to work...nice...
P.S. And to all of you that keep screaming about putting all of our resouces into alt enegy...you mean like cancer for decades? Throwing money and people at a problem doesn't guarantee success. And what about in the meantime? Do nothing? Nice plan.
