It is a bit silly really, regardless if it reaches number one or not the xfactor single will still have the same amount of people buy it and pocket mr cowell the same amount of £££.
By selecting another song to push to the top spot, you just give lots and lots of cash to another artist.
The ironic part is the fact that people are attempting to fix it so xfactor cannot win because they are annoyed that it is a foregone conclusion that they do win every year.
It's ironic because they are attempting to fix it to beat what is considered a fix every year anyway.
