A Miscalculation by the Seattle School Board?

Cliff Mass (of local meteorlogical fame) and The Seattle Courant both have posts about the Seattle School Board's choice for their new math books. The Courant was fairly neutral, simply stating that there has been opposition against the Discovery Series, the school board's choice for their new math textbooks. Cliff just came out and said that he thinks that the Discovery Series sucks. I have not seen these schoolbooks, so I can't offer my personal opinion... I wonder where I'd have to go to get my hands on some to check out.
