Hello Maverick,
this is what I have on FF console loading CJ Community Poll (1.5.27) page, with CJ Community Answers anything seems to work fine.

jQuery is not defined
b[e][1].apply(a.element,d)}},contains:...c.ui.isOverAxis(b,e,i)}})}})(jQuery);
.../plugins/corejoomla/jquery/jquery-ui-1.8.11.custom.min.js (line 17)

jQuery is not defined
})(jQuery);
.../plugins/corejoomla/jquery/jquery-ui-1.8.11.custom.min.js (line 813)

jQuery is not defined
})(jQuery);
.../components/com_communitypolls/templates/default/scripts/polls.js (line 418)

jQuery is not defined
jQuery(document).ready(function(){PollsFactory.attachHandlers();});
...on the poll page.

Thanks,
Fabrizio
