The current electoral system is one of the cornerstones of democracy.
I remember my father moaning at me because I opted not to vote as a teenager, and he rtold me that people had fought and died in the war to give me the vote. I replied that actually, people fought and died to give the CHOICE of whether or not I vote, and to take that choice away is to make the essence of freedom redundant.
If politicians are worried that apathy in the electoriate is growing, they should do more to engae the young voters, and make it apparent to them why choice is important.
The hoary old get-out that 'they are all the same' is increasingly valid - and that is the fault of the politicians, not the voting system.
Anyone who thinks that compelling people to vote will suddenly cuase an upsurge in thoughtful committed intelligent voters who carefully consider the arguments, manifestos and personalities involved, before they vote, is living in a dreamland.
