Speaking of aesthetics, it will be interesting to see how the physical differences in Obama and McCain affect the election. According to WikiAnswers, Obama is 6'5 and McCain is 5'7. If I were McCain, I'd ask for a phone book to stand on during debates. Just kidding. Kinda.
Also, Obama is 47 and McCain is 71. How will these things affect the election? Should they? Whether or not they should, they will.
