In case anyone missed this: Bush's own science advisor concedes that Intelligent Design is bunk or "not a scientific concept" in his own words.
Pity Bush doesn't understand this himself.
Evolution is not "just" a theory. A theory is a big deal: theories can be subjected to obervable, repeatable testing. ID cannot. Therefore, ID ain't even a theory. But the fact that evolution qualifies as a theory (buttressed by facts) is incredibly significant and its importance shouldn't be undermined because some wish to surrepticiously mix religion into science.
Look at it this way and the whole topic is really the stuff of Science 101. To agree to consider ID as science is to breech the scientific method. Clear and simple.
