It basically says that even though at least 60% of the country are basically left wing i.e. they think that government policy should be ultimately routed in social justice. This 60% are also too fickle and unfocused to have one practical ideological position and their votes are consequently spilt up amongst different parties. On the other hand you have a right wing who, although in the minority and only managing about 36% of the vote even after the most disastrous Labour administration in living memory, are nevertheless a tribe broadly represented by a single party. (There is about 14% of the vote which gets filed under ?other?. These are the racists the commies and the IRA.) In the current system this means that while the right can under favourable circumstances only muster 36% of the vote they can quite easily end up with almost all the power. This is either the fault of an unfair system or the fault of the left for being too useless to present a unified front. Either way under AV the result will be that the left is better represented and therefore the government will be more representative of the population i.e. fickle and unfocused. This is the problem with democracy. People can?t be trusted to know what is good for them. If people had their way we'd probably have a laser cat economy, monthly oral sex holidays and juggling policemen.
