The British series Dispatches covers the election process in Britain, and how the system has changed to use a computer model to target voters in specific regions based on promises that nobody could disagree with, basically making promises they don't intend to keep, whatever will get them elected, while avoiding the true hard issues that people want them to deal with that will hurt business, cost votors more money and help the environment. Basically it shows that we are offered several identical candidates and no real choice - just like in the USA.
