I find it disturbing that McCain just said he'd like to see a man on Mars. There's an echo there (or course) of JFK pledging to put a man on the moon. That's not what we need. We need gov't to fix our energy problem -- to a large extent that means getting out of out way, and allowing us to access our own resources. It means making nuclear energy plants easier to approve. It means opening ANWR.
There's a lot we could do. Talking about Mars isn't going to help.
I disagree. The country needs to invest in new technologies, and one of the best ways to do that is to set a goal and work toward it. Spin-offs from the moon program led to the high tech revolution, and that program has paid for itself many times over. We need to do it again.
