Anyone, given the strength of their qualities, can become a Member of Parliament. There is an argument that if you feel strongly about politics you should make the commitment in time and effort to become an MP. The party political process selects the best candidates to stand in elections by a process of "survival of the fittest".
Interactive Democracy recognises that not everyone can become an MP and contribute to public life in that way. There are only 646 seats in the house of commons meaning that vast numbers of intelligent and conscientious members of our society are unable to contribute to political life as much as they would like. Indeed, by dint of their experience, many of these people may be extremely well qualified to vote on individual issues.
