Bieber playing reverse psychology lol. If he loses no. 1: "Justin Bieber decides to forfeit his number 1 lead in aid of charity" etc. ....... even though NHS would have taken it anyways since the gap has closed significantly. But now if they are "suddenly" and "unexpectedly" number 1 in tomorrow's update many will be attributing it to his support. Nice calculated PR move there..He waited to tweet his 'support' until he knew the race was over
