Polls are identified by the MD5 hash of everything inside. Even minor differences, like adding or deleting spaces or carriage returns, changes the content and, therefore, changes the poll.

You can move the poll around, include it on multiple pages, wrap it in whatever markup you want, and it's the same poll. Change something inside and it becomes a different poll.
