If you're too young to vote (like me), make sure your parents do. Offer to do more chores, promise to finish your homework by 8pm -- just make sure they vote!
P.S. Yes, I am an ardent supporter of Barack Obama. I've been following his career since I was in seventh grade (I'm a senior in high school now) -- his websites have been bookmarked on my web browser since then. I know a lot of people (including my own friends) doubt his ability to bring about the change that he speaks of -- and yes, a politician is different from an inspirational leader like Gandhi or Martin Luther King, Jr. -- but Obama has demonstrated the potential to change things. In the words of one of my friends:
He has the ability to climb mountains at break-neck speed. He jumped from community organizer to state senator to US senator to presidential nominee, beat out Hillary Clinton as the underdog in the primaries, became the first black man to be nominated for the presidency by a major party, and won the world's support and approval in the meantime. -- Katherine R. LongAnd we, the United States of America, need to climb mountains again.
