Any poll conducted by any organization is absolute Bravo Sierra unless they show you the internals of the poll. Legitimate polling organizations have a reputation to build and maintain. They release the internals.
When I see a poll I immediately go to the bottom and read the interanls. If they do not show the internals I do not even bother to read the poll results.
