Some folks always have scapegoats. They rely on them to take all the blame for everything so they don't have to. Do you have one too?

I wonder how people choose which goats to scape? Vote? Take a poll and see which is most popular? Follow the party line and go along with its soup du jour/piece de resistance selection? How long does that scapegoat last? When is its time up and a new one takes its place? Do some goats have lifetime tenure?
