This is not true and I don’t like hyperbole. Lets us look at facts:
Event qualifying Race qualifying gap circumstance
Lewis /Jenson Lewis/Jenson
Aust 2/4 2/6 5tenths to Lewis
Malaysia 2/4 8/2 3tenths to lewis penalty for lewis

Abu Dhabi 2/3 1/3 0.009 to Lewis
Brazil 4/3 Ret/ 3 2tenths to Button.
This is the only race where Jeson beat Hamilton squarely in qualifying without incidents. Race however Lewis had a gearbox failure and retired.
Button had two retirements versus Hamilton three.
Button won three races and Hamilton three.
Looking at these results there is no way you would say that Button dominated Hamilton. I would actually put it the other way round by qualifying but points are not made in Saturday. However the retirements and incidents at races affected Lewis more and final tally does not show this. It is strange when people also add the points for three seasons and say Jenson beat him over three season. A championship is one season not three years.
