http://musicmachinery.com/2009/04/15/inside-the-precision-hack/It is called a "precision hack" and was orchestrated by viewers of 4chan. "moot" is the founder of 4chan (darn him, he stole part of my ubiquitous Internet name, grumble grumble...)
Looking at the first letters of each of the top 21 leading names in the poll we find the message “marblecake, also the game”. The poll announces (perhaps subtly) to the world, that the most influential are not the Obamas, Britneys or the Rick Warrens of the world, the most influential are an extremely advanced intelligence: the hackers.
At the core of the hack is the work of a dozen or so, backed by an army of a thousand who downloaded and ran the autovoters and also backed by an untold number of others that unwittingly fell prey to the spam url autovoters.

I have not seen any reference yet to whether Time will be jettisoning the results of this poll, but I think the current results are... moot.
