I'd better start by saying that I don't actually watch X-Factor, except when the wife has it on, but it is hard to keep away from it!
I am guessing the twins have gone through again, lol.
As much as people think it is unfair/fix/ridiculous/etc it really doesn't change anything. Nobody is going out who would have won it. The winner will still be the same person/group whether the twins went out first week or the finals. The result remains the same.
I could be wrong, but I bet most of the people complaining don't even vote? I know I wouldn't!!
Currently there are still lots of acts, and some seem quite good, so the total vote is splitting across a lot of outcomes, and the strong support the twins has is seeing them through. As the amount of acts drops, so the total amount of votes will not be spread so thin, and sooner or later they will be out.
Getting a little serious now, but kinda makes me think of the BNP! They get much further than they should, because not enough are voting for the others!!! Art imitating life
