I would argue that what you want isn't actually the ability to edit polls, but the ability to close polls and create new ones within the same thread. Editing active polls isn't really a good idea, and editing a thread's poll in order to ask a new question would keep people from voting on the second question if they voted on the first one.

The only defensible reason to be able to edit an open poll would be to fix a spelling mistake in an option or something.
