What you vote for either democrat or republican and that being independent means that you dont vote.?? or as we call them no voters.
In the US the only two parties politicans are normally affiliated with in a federal election are Democrat and Republican. Usually someone runs under one or the other party. However, there are some candidates who run as independents, meaning they run with no affiliation to anyone. They are their own man or woman.
When voters call themselves independents they generally mean they don't support any one party over another but will likely make a decision to vote based solely on the people running. They could vote for a democrat or a replublican, or anyone else for that matter. They aren't maried to either ideology and will cast a non-partisan vote.
Usually the occasional politician will break ranks with his party and become independent. And some are successfully reelected. I believe Joe Lieberman is one. http://lieberman.senate.gov/
Being independent could be like being a third party in a minority government. If the numbers add up, your vote may hold the balance of power on some congressional voting issues. Or it might not mean much. It all depends on the structure of the elected congress.

Nor can you blame innocent American victims for Bush's crimes.
Suppose some madman took a shot at someone - should you take the blame for it? Of course not.
