And ID is not theistic evolution. (link)

And criticizing the legal decision does not entail supporting ID. It's entirely possible for bad legal decisions to do something good, like ban ID in the classroom.

Objection #2: Intelligent Design Rejects All of Evolutionary Biology

The Short Rebuttal: Intelligent design does not reject all of evolutionary biology. ID “does not challenge the
idea of ‘evolution’ defined as either change over time or common ancestry, but it does dispute Darwin's idea
that the cause of biological change is wholly blind and undirected.”

Where did I get this? Glad you asked; page 7 of the Discovery Institute's The College Student's Back to School Guide to Intelligent Design.

Also, if you read the Plantinga article previously linked, Plantinga was not challenging the legal merits of the Dover decision. He was specifically challenging the conclusion that ID was not science which made the decision possible. Plantinga's argument was that ID is science. This is a clear demonstration of Plantinga's support for ID.
