If you are wondering about negative stories concerning any of the presidential or vice presidential candidates, a great way to check it out is by going to http://factcheck.org/. It's a nonpartisan site that debunks lies in politics.
A more general site that's good for rumors, urban legends, and virus scares in general is at http://www.snopes.com/. I try to always check those emails that get circulated about free money from Microsoft, Sarah Palin's list of banned books, etc.
