Torture: The Candidates Positions

Barack Obama: Opposes all torture.
The secret authorization of brutal interrogations is an outrageous betrayal of our core values, and a grave danger to our security....Torture is how you set back America’s standing in the world, not how you strengthen it. It’s time to tell the world that America rejects torture without exception or equivocation. (source)

Hillary Clinton: Opposes most torture.
Has opposed the general use of torture but has stated her approval of torture for the "ticking time bomb" scenario and when the use of torture is approved by the President. (source)
In the event we were ever confronted with having to interrogate a detainee with knowledge of an imminent threat to millions of Americans, then the decision to depart from standard international practices must be made by the President, and the President must be held accountable. (source)

John McCain: Opposed but not fanatical.
Has made something of a name for himself by opposing the torture of prisoners held by the United States. Supported S. 3930 which included provisions indemnifying CIA interrogators who have tortured prisoners. Thinks waterboarding is funny. (source).

Mike Huckabee: Opposes only for humans.
Has stated opposition of the torture of humans but has supported the torture of animals. (source)
