These polls Fox do on O'reilly and Hannity and such are used for their own use and not for public view. They use these polls to guage if their "blackout" of Ron Paul is working and are curious to see if his votes go up or down when they post a new poll. If the votes go up, that means they have to do more smears against Ron Paul, if the votes go down, they sit back and laugh and gloat over their unfair and unbalance strategy.
I say the next poll that they post, we do a total "ignore". No one post a vote. Then watch how fast that poll hits the airwaves. Someone who has a screenshot of the last 4 or 5 polls Fox has posted and never shown should keep them in reach. When the next poll is posted and we ignore it we can compare the numbers. Now we can't stop everyone from voting because there are probably just everyday folks voting that don't belong on these boards or other RP forums. But it might give us a guage of what kind of real support is out there without our votes.
