Done a couple of these: One potential way of approaching this is simple cookies - drop a cookie as to whether or not someone voted - (granted they must have cookies turned on).
Forced registration before polling, (something simple like email input) - to track responses. Used in conjunction with the cookies you can effectively strip responses from those that abuse the system. And now for the really creepy one: given that a majority of browsers are using an IE/Win combination there's this: http://www.computerbytesman.com/privacy/supercookiedemo.htm But as you can see, cookies/JS are about the only effective way to identify a client: but building the system to detect and store responses (building identifier hidden form fields with JS) based on whether or not it was a "clean" poll will allow you to at least filter out multiple or invalid responses at report time.
