Here is a fairly short, 25 minute overview of the American political landscape that Thomas Frank delivers in The Shaw Address in Australia.
He urges them not to go down a similar path in 'this low, dishonest age.'
"Where such a shift in power is in favor of the governing elite, Power will achieve its murderous potential. It simply waits for an excuse, an event of some sort, an assassination, a massacre in a neighboring country, an attempted coup, a famine, or a natural disaster, to justify the beginning of murder en masse. Most state sponsored murder occurs under the cover of war, revolution, or guerrilla war, or in their aftermath."
