You understand that there aren't even close to enough Hey Monday fans to swing this thing, right?
This isn't Yao Ming, where all of China votes to make him an all-star. Hey Monday had a following, but this is national television we're talking about.
I believe that although the show has a lot of viewer s not many of them actually vote. The people who have followed her before and the ATL kids who probably don't even watch they vote because the guys tweeted asking them too can give her an advantage over other contestants.
