Frustrating search!
I recently read a quote from Bush Sr. where he called for manned missions to the moon and mars. Can't figure out where they are, so you have to trust me. Anyway, it came to nought, so I wouldn't put too much hope in Dean or any other politico.
Though I did run accross: "Mars is essentially in the same orbit...Mars is somewhat the same distance from the Sun, which is very important. We have seen pictures where there are canals, we believe, and water. If there is water, that means there is oxygen. If oxygen, that means we can breathe." .Governor George W. Bush, Jr., 8/11/94
Also, W is the antichrist -- I saw the astrological proof during my googling, so it must be so.
