the thing with IP addresses is that many users, like anyone with AOL, have a new IP address assigned each time they go online - sometimes, it changes every time they click a new link. The only REAL solution is to make a user log into your site before they vote. Then you can track who has voted and who hastn't.
(of course, the user may have more then one user account, but this is still more efficent then the other methods)
since the log in makes a voting poll a bit cumbersome - in the end, really, I guess all you can do is remind users that this is not a scientific pole and the results may not accuratly portray your demographics true opinions.
