a Ghoul?

I can't think of the word to describe exactly what my thoughts are concerning President Bush's heartless attempt to cash in on the suffering of the people of New Orleans. Bush and his team have diverted valuable resources in money and manpower to stage a photo-op in the midsts of all the suffering only to portray themselves as caring. After the pictures were taken and Bush departed the scene, the staging was torn down and nothing remained except the illusions created by the pictures. To my mind, Bush is feeding on the dead. What a callous bastard he is. Actually, the only word I can find to accurately describe him is: a ghoul.
