Again, it wasn't billed as such in the beginning, just a "hey, who would you guys like to see make it" never saying "the winner will be put in". Otherwise why not throw a bunch more fan favorites into the mix and have an actual "fan favorite" instead of "fan favorite from a small pool of characters"? There's no way to determine if this was a fix or an error on the part of NRS or the site they used so I wouldn't state that as "fact". If it's just a lie then why even have the poll at all? They knew how many people wanted Lobo in without a poll so they put him in, it could've been the same for Zatanna if they wanted. It doesn't matter because, again, Batgirl lost the poll against Powergirl and Supergirl, she was in third place no less, but still got in over the other two. It's about who NRS and/or WB decide to put in ultimately, there was a lot of support for Lobo and Zatanna so they got in.
