I just don't get exactly what you mean by "political agenda" that ID people have. How do you think politics is involved?
ID was created not to provide better science education, but to put a version of Christianity in the classroom. That was the stated purpose behind it originally, and it was the admitted purpose of the Dover school board (although they perjured themselves in an attempt to deny this).
And that's the difference.
ID was created to further a political goal, and the Theory of Evolution was formulated as a response to the physical evidence.
Now do you understand the distinction?
