this one is working for me

you may also need to install something like GD BBPress Tools to activate shortcodes in forum topics and replies if you want to embed a poll in a forum post

Just be aware that activating shortcodes in bbPress can open up a whole can of worms, which is why its disabled by default.
If they are enabled there is nothing stopping someone from using bbPress shortcodes in a reply/topic, eg [bbp_login].
Polls in 2.x is definitely something that is needed. However it’s really plugin territory, and so far no one has written one!
Aww I really want this, cardoza wordpress poll doesn’t seem to exist anymore or at least I can’t find it in wordpress plugins list
Unfortunately at this time there is still no poll plugin or capability that exists for bbPress 2.x.
It can certainly be done, however will require some coding knowledge and a little bit of elbow grease.
hmm, the other plugin i listed earlier seems to have been pulled from the wp plugin directory, authors page for that plugin is here – http://www.vinojcardoza.com/cardoza-wordpress-poll/
this poll plugin is still avail and also works fine w bbpress 2.3.1 via shortcode

note that shortcodes in bbpress may create other probs as jared mentioned above, using plugins like these will allow you to specify allowed shortcodes via whitelist and exclude [bbp_login] etc

and this one will allow shortcodes by user role
