This page gives the impression that a Polls Add-On exists.
However, there is no download available here.
Also, there is nothing in the Add-Ons browser from the dashboard of my site. If this does exist, please remove it from the documentation pages. My belief that this was available was one of the reasons I upgraded my license. Yes, I know I should have checked more thoroughly before I upgraded. It's likely I would have upgraded anyway. But still, imagine my disappointment to pay for something, only to find that it was not available.
