If you're still undecided at this point, try this little mind-clearing exercise:

Find a quite peaceful place, assume the lotus position and begin chanting "Om". Now, there are only two sounds in the Om, those being the vowel sound "o" and the consonant sound "m". Just by coincidence, those happen to be the first letters in the last names of the two major party presidential candidates. Continue chanting "Om" until you begin to feel an afinity for either the "o" or the "m". If you feel the "o" speaks more clearly to you, vote for Obama. If you feel the "m" speaks more clearly to you, vote for Cynthia McKinney.
