In short, it would be an online website presenting itself as a hypothetical political party which would give honorary membership to candidates in an election who meet the stated objective standards of this hypothetical party (i.e. who would have met the standard for membership had it been a real party).
It would essentially serve as an objective educational website, a little like political compass.
As an example, let's say this virtual party decided to name itself the Party for the Universal Declaration of Human Rights, and had a site like pudhr.ca or something of the sort, and gave honorary membership to any candidate in an election whose election platform did not conflict with the UDHR in any way and was advancing at least one of its principles, it would be a quick way for voters to learn about their candidates on one convenient website.
Of course other variant 'virtual' parties could exist too, such as the Party for the X, Y, or Z, all based on the some kind of objectively verifyable criterium. Any ideas on this idea?
