BTW, my original idea (which is now bunk) was that the person who hired the Drazens is in the Palmer camp and that he hired the Drazens to kill SHERRY Palmer. This would have eliminated a rival for David's ear and eliminated a problem for David. Personally, I think that would have been cooler than David being the target.
Still, I think the producers have one more surprise for us. BTW, the name of my "puppet master" was Mike Novick -- the nerdy chief of staff -- nobody'd suspect him, yet he's wherever the action is.
