That gets into issues of definition
Bush is a socialist it the traditional manner.
I'm guessing that your definition of socialism is a bit different then mine.
To me, Socialism implies that the government either owns or strongly regulates major industries. While the US government on paper does have strong regulations, those regulations are often written by the industry they are supposed to regulate and changed when that industry wants them changed. Thus real control is much lower then the pile of regulation would suggest.
All resources/people belong to the state. The state decides who receives the rewards.
I would consider the idea that everything belongs to the state as true of both communism and facism and not true of proper socalism. And Bush leans a lot more towards the facist then communistic end of the spectrum.
