Bush is not the problem. His administration is just doing what a multitude of people, past and present, are doing: picking a preconceived position that sounds good to them, and finding bits of science that back them up without looking at the holistic picture.
On global warming, stem cell research, and a variety of other issues, this is evident on any side of the debate, whether you're a Democrat, a Republican, or an independent.
This isn't even a "people in power abusing it" problem: this is something that extends from the most powerful (Bush) all the way down to Joe Sixpack Everyman, and it starts when we convince all our kids in grade school that "Science" is all about discovering black-and-white, set-in-stone facts about our universe that never change and can be easily regurgitated on multiple-choice exams.
I'm a medical student with a Bachelor's in both business and microbiology. Let me say this: if I had stuck to the introductory science courses required by my business degree, I would still have this misconception about what science is, and how scientists go about their business.
And if it takes an undergraduate degree in a true science to finally have it explained to you that sometimes "It depends", "Sometimes", or "Within certain parameters" are actually valid answers to scientific questions, what does that say about the 95%+ of the rest of the population that never finished high school, never went to college, or became English majors (poor souls ;))?
Singling out Bush, like I've said above, provides a convenient scapegoat without looking at the real problem or how to solve it: "Oh, look at Bush! He's so eeevil! He's distorting science to fit his viewpoint!" The unsaid conclusion to this, of course, is that if we get rid of Bush, or even Republican politicians, that this will somehow be fixed.
""Neither ideology nor policy concerns should constrain the research agenda in any way," said Dr. Alan Leshner, CEO of the AAAS. Leshner said there is a "frightening trend" in this direction now, in which scientists whose findings appear to run counter to the dominant political or cultural agenda are losing funding or appointments."
The sad part is that Dr. Leshner calls this a "trend", as if this were something new, instead of the reality of the commingling of science, public funding, and public policy for the last.... hell. Louis Pasteur was manipulating this same kind of system back in the 1800s in Europe.
