To be honest, even though there are 4 drivers who could still win it, there are only 2 drivers who will win it. Alonso and Webber, it will get to the point where Red Bull have to back one driver over the other, and that will inevitably be Webber as he's the one who has got more points at the moment.
Did any of you hear Hamilton's radio with his team today, he couldn't stop moaning about something that was going wrong with the car, i think he's slightly frustrated at Mclaren at the moment, but you could see he just didn't have the confidence to put the foot down today, which isn't like Lewis, he's usually pushing the car to the absolute maximum. However, just think, if he hadn't got too hot-headed and crashed out of those races (Monza, Singapore etc.) He could still be in with a decent chance of the title, now he's forced to hope that he can win at Abu Dhabi, and that the other 3 decide to take each other out. It won't happen.
