Lets see if we can figure out the satire--again not trying to be political, just trying to guess why each president picked for specific roles.
Reagan as the Mummy is obviously because of his age.
Clinton as the Wolfman because men who chase the girls are known as wolves(*ahem*)
George W. as a Zombie because Zombies want brains and he was accused of not having one?
Obama as Dracula because of criticisms he is draining the country dry?
Kenneday as the Phantom because he wore a mask that hid his secret turmoils (Marilyn, etc.)?
I am stumped on Lincoln and Nixon though....unless its because of physical characteristics such as Lincoln kind of looking like Karloff's Frankenstein and Nixon's jowls being compared to Creechie's gills.....
