I voted for Alonso, it's a big lead. The Ferrari cars last gremlins I can remember was in Malaysia 2010 where Alonso's engine blew up. Add to the fact that the team not known for great pitstops or strategy after Ross Brawn left, have been terrific this season. I feel the team doesn't get much credit for this when they should. Then there's no team-mate getting in his way.
For all the others, they'll be tripping over each other, as it different tracks different cars excel, while the Ferrari and Lotus have been the consistent ones so far. Then there's the equal oppurtunity aspect for both Lotus and McLaren drivers, fair enough for Red Bull as they both are so close in the championship. In a season like this at this time of the year when there's a clear number 1 in the standings you have to back him no matter what, but I don't see it happening at McLaren or Lotus.
Unless Alonso has non points score, then I fear the title is over, unless we have another 3 races in a row where Alonso finishes 5th-7th like in Hungary and most of his rivals gain on him.
Out of the 5, I would like it if Kimi Raikkonen won. It would be great, as he's been great since his sabbatical, plus I'm a fan of his, and the Lotus car just looks bad ass. But if not him, then Lewis Hamilton, I'm no way a fan of his, but he's been ever so unlucky this year, but he's kept his head down and delivered, kind of a contrast year for him compared to Alonso.
Webber's had his car problems often, but at anonymous and does a Rosberg.
Vettel has been unlucky on a few occasions, the sliced tyre in Malaysia, the penalty he and Massa for in Spain, and we all remember Valencia.
