I'd like to see him do it. His driving has been far better than either of the main contenders' this year and has only made one error compared to the five or so that Massa and Hamilton have each made. Of course, it's not realistic, but we can hope, eh?
The only reason I want to see Hamilton win the title is because he is an employee of McLaren. In terms of who has been the best driver this season, it almost certainly has been Kubica.
