I hope to convince Americans (particularly children) that they are selfish and destroying the planet. I picked a first-rate eco-loon as my science advisor to help accomplish this.
I hope to use this fear to keep Michelle and myself in the White House for at least six more years (she loves our cool house and having taxpayers pay for our lavish lifestyle.)
I hope to get many people dependent on the government, so they will be grateful for the crumbs we occasionally toss them. My buddy Hugo says this is a very effective technique.
