I thought lewis and button both extended their contracts 5 years $100million??? Only way Lewis would go to RB is if Vettel Goes to Ferrari and that aint happening. Mclaren and Hamilton have stood by each other for a long time and it would be catastrophe for them to split. Hamilton is a great driver. He knows how to win and Mclaren Showed Great pace this past weekend and that only boosted Hamilton's confidence in the mp4-26. Lewis will no doubt be a front runner come Valencia.
Seriously don't count on it not happening.

Lewis wants to win and he needs the right car to help him do that. McLaren are not as formidable as they once were,they really haven't got anyone who can match Adrian Newey in the car design department so RedBUll will run away for the foreseeable future. RedBull want to dominate they want a legacy and a history matching McLaren so they need two of the very best drivers to pull that off.
Mark Webber is not the driver to do that alongside Vettel and believe it or not Vettel and Hamilton go back a long way. I really have nothing against Vettel i actually think he is a down to earth young chap who has the same will to win as Lewis but hasn't got the same killer instinct. RedBull will pull everything out of the hat to get Lewis on board, make no mistake about that.
Right now Lewis is trying to push a car that is not up to scratch beyond it's limits and is paying for it whether it's his fault or the other persons fault the car cannot give Lewis what he wants. Let McLaren have Jenson Button because with Lewis gone and Jenson in the drivers seat they wont win anything.
I am a McLaren fan and have been all my F1 viewing life but they are letting both drivers down and making far to many mistakes under Martin Whitmarsh. RedBull are on top of their game and it burns me to say it but they are miles above the other teams in work ethic and partying when the time arises.
There pits tops are outstanding and they really have the strategy up to 99% right,why wouldn't Lewis go to their team.
Expect to see more of this as the season continues.
