The gentleman compiling the AP tally has been interviewed and stated the Caucus results the tally shows are from the (meaningless) straw polls conducted in the state. The delegates themselves have been confirmed with the state, and the state's chairman was replaced with a Paul supporter. This can all be confirmed without using YouTube videos.

Did Paul clench the nomination? No. But the media is being misleading by claiming Romney / Santorum got the most delegates in Iowa. In that state, Ron Paul won.
