For those of you who are interested in a good website to search a politician's background and voting record, one of the sites I like is called Project Smart Vote at http://www.votesmart.org/
To make it easy for everyone:
Obama
http://www.votesmart.org/bio.php?can_id=9490
Hillary
http://www.votesmart.org/bio.php?can_id=55463
McCain
http://www.votesmart.org/bio.php?can_id=53270
I highly encourage everyone to take time to vote based on prior history and facts. Can the candidate do what they say they will do? Have they been effective? Do they have a history of flipping on issues? I'm sure everyone has their own hot button issues so explore. To my knowledge, this website like factcheck.org, is largely apolitical.
