But now that i saw Button finally struggling a bit with the balance, I went for Vettel. I think Rubens finally knows what's best to do and that's going for his own skin.
That could mean we will see Rubens more in front of Jenson.
Buttons car has problems when it´s cold, He can´t get temp in the tires.
Vettel is outstanding in the wet but in warm climat he don´t stand a chance against Button, and also the experience will matter in the end so i go for Button.
I think Vettel can win it cause Red Bull made a huge step forward with their improvements and I think they'll be hard to beat. Brawn GP is in a hard situation, as they were from the beginning of the season because they don't have that much money as the "other teams". Ferrari and Williams came very close to them and that makes their situation even harder. But also Mark Webber has a chance at the moment I think, he's really close to Vettel and he could do the laps Vettel could do after passing Barrichello. Barrichello only has chance if really his help on the car setups brought Button to the top. If Button can't setup his car but Barrichello can, and Brawn GP somehow manages to get back on top, he can win.
Massa doesn't have a chance this year I think. He's too far behind. I would be happy if he won but he won't.
