The wrong person went home and should never have been in the bottom two.
Lloyd, John & Edward and Danyl all gave weaker performances than Jamie did.
In the sing off Jamie gave a good performance and Lloyd was bad he was off tune at the beginning, picked up a bit in the middle and lost it again at the end, so how can you save someone who gave a bad performance

Lloyd and John & Edward should have gone a long while ago and are only staying in because of the little girls voting for them. Most adults will only make one vote possibly two, the little girls will vote 10 times or more. I think they should change the voting so that only 1 vote can be made from each phone so we get a true idea of who is popular instead of a distorted one when people are making multiple votes. Other competitions can regulate votes so X-Factor could except they are more interested in £££££££££££'s than finding the best singer.
Louis should be sacked, please get rid of Louis and leave it at three judges there couldn't be a tied vote then either.
