From the "Security" section of his main "Blueprint for Change" (http://blatantreality.com/wp-content/uploads/2009/05/obamabl... p. 71):
>Reaffirm our Values: Obama and Biden will restore respect for the rule of law and America’s values. They will: reject torture with- out exception or equivocation, including so-called “enhanced interrogation techniques” like waterboarding; restore the Rule of Law by closing Guantanamo and restoring habeas corpus; and provide our intelligence and law enforcement agencies with the tools they need to track down terrorists without undermining our Constitution or civil liberties.
Similar statements are made in other 2008 campaign documents, and with more detail.
Before you object, I do realize you're saying two different things here: (a) that it wasn't one of the "main" things he ran on, and (b) that promises to restore civil liberties "weren't really there" except in liberal imaginations. I can accept the first, but the second is completely untrue.
