George W. vs. Clinton-- who would win?

Interesting, Taegan Goddard is reporting that Democrats might support allowing naturalized citizens (such as Schwarzenegger) to be elected president if the Republicans support repealing the 22nd amendment which restricts the presidency to two terms. That would allow Bill Clinton to run for another term. It would also allow George W. to run again. As much as I'm curious to see who would win between the two, I hope that this idea doesn't go anywhere. The only thing keeping me going right now is the fact that W. can't run for another term.
