Wouldn't it be cool if we could have alternate timelines and get to try out both Obama as President and McCain as President on two different timelines?

See how it would turn out either way.

Then you come back to the present and show everyone how it would go in a video. Everybody goes out then and votes for the one who screwed up less badly. ;-)

This would save one HECK of a lot of money, time, trouble, and hot air, wouldn't it?
