Amongst the voters for the presidential debate tonight will be �Joe sixpack.� The American political scene carves up the electorate into sectors of mythical power, something the British are good at too. During the 80s and 90s, talk was of a man named after a car similar to that of a Ford, so likely to be a voter in the late 20s with a mortgage and ready to settle down. But it’s hard to find similar voters elsewhere. Egyptians have a kind of John Doe, but quick calls to Denmark, Italy and Greece, amongst others, failed to come up with similar comparisons.
