And in terms of sending empty instead of full bags. I think the overreaction is a better reason to send the full bags. To the extent that the post office and such overreact, it is more effective. If they panic every time a bag of rice goes through to mail directed at the President, more strain is put on the system. It makes a much more effective "cost raising" tactic, than if they ignore it. And they look like panicky fools. So yes, send a half cup of rice to the white house.
