Sam Bailey has been revealed as the singer topping the X Factor Live Shows each week with 35% of the vote. The Sun has said that the singer is miles ahead in the competition and Nicholas McDonald is in second place. A source told the paper: "Sam Bailey is so far ahead it is unreal. "She's the runaway leader, a million miles in front of her nearest rival and, if it was the final this weekend, she would romp home. "Viewers love her voice and have really taken to her back story. She is a mum who has worked in a tough job and people seem to relate to that." Sam Bailey is topping the X Factor live vote each week Tamera Foster, who is reportedly music mogul Simon Cowell's favourite contestant, is in sixth place. The source added: "He wants Tamera Foster to win. He has publicly said she is a star and he genuinely thinks she could be massive internationally like Leona Lewis - but she isn't connecting with the public. "She's already been in the bottom two and Simon is frantic she improves her position." Contestant Sam Callahan, although criticised by judge Gary Barlow for not having the best voice, is performing well in the live vote according to the insider. "If the voting carries on as it has been, the final is looking like Sam, Nicholas McDonald and Sam Callahan - surely one of the most boring ever." The theme for this week's show is Great British Song Songbook; tune in to our Live Blog on Her.ie this evening for updates from the live show as it happens.
