At the very least, you can overwrite the poll page with something else. At least that would get rid of the redirect. But I agree with Fandyllic, I don't see anything that would prevent a local admin from deleting the page. There shouldn't be any special protection on it since there is no "Poll" namespace (|namespacealiases&format=xml see here). That means the page is just in the main namespace like any other normal article page.
