Yes, but given that the two dominant teams in F1 in recent years (and the two with probably the biggest budgets) have now found form Red Bull and Brawn will probably be fighting over the minor placings where there is only 1 point between placings, so the chances of him catching Button are slim. Likewise though, the only person likely to challenge his second position is his team mate, Vettel (I know Barrichello could, but I don't think the Brawn team has the development potential to catch up to Red Bull who are obviously faster than the Brawn's now).
