I am an attorney in PA and when I get my mind working on a case it's sometimes difficult to let things go. I watched the Quicktime movie and am convinced Kerry cheated twice. Once clumsly to throw suspicion off and the real cheat.
I think The Post and the DNC are accurate that Kerry pulled a pen out of his jacket. This was done with no thought of concealment. However his right hand contains a white object just visible as he rounds the podium. The papaer is then seen again and is folded over at the end of the clip.
He opens the pen that he pulled out which allows him to cover his right hand as he opens the paper up. Look at the video again. Now it's not just about cheating, it's about lying to cover up the cheating.
Looking at it again I don't think the object in right hand is paper. Watch his right hand very carefully he "Snaps" the item closed. You don't and rally can't do this with paper. I am now thinking some kind of wireless device.
