Ya I don't trust the votes either. What was it a year or two ago...wasn't it like Edge and someone else vs. then 2 ppl who were voted in. Rey and Matt Hardy get voted in, then Edge disappears. This was after the Matt, Lita, Edge deal, and they probably weren't ready to have Matt go over Edge since they just had Edge beat Matt and move him to SD. So that's a decent example of them changing the card to avoid a fan vote choice.
Another thing is they give you two ******ed options and one really good one usually. Like Batista vs. (you get to vote Khali, the brooklyn brawler, or Rick Steiner), and the stipulations are (vote match type, steel cage first blood hardcore match, tutu match, chess match).
