Teams of men from MI5 will no doubt trawl through the whole lot, doubtless looking at all the interesting candidates first. Unless anything goes wrong, they've got five whole years to work out the rest. They'll have computer scanners and electoral databases to speed it up. So any anarchist voters in a future election would very quickly find themselves on the black list. The idea of representation is the main problem with elections.
Representational democracy is grounded in the principle of exclusion.
Ordinary people don't get a look in, you don't get members of the public making speeches in the House of Commons, nor are we allowed to vote in those division lobbies. Because there is this representation principle, the whole thing is utterly disconnected from outside. What we need to do instead is build up positive alternatives of empowerment. We need to initiate hundreds of small, inclusive, participatory democracies, where people are involved in all decisions. One fault with representation is that it makes people passive.
