The underlying premise of Interactive Democracy is that together, voters are capable of making good majority decisions. This comes from enhancing the quality and scale of the debate. Some may question these assumptions.
The party political system, as it stands today, provides a limited number of candidates and, in their competition for voters support, the best team emerges and is allowed to form a government. What I think about an issue and what you think is irrelevant. So long as someone votes, one flavour or another of the political elite (and their financial backers) will gain power.
