I've spent too much time this year at work, explaining the 3-5 Levels of War to people. But Khairy Jamaluddin's Malaysia General Election campaign is a great medium for such discussions.
1. Technical layer : you know how to vote
2. Tactical layer : you see a good parliamentarian, so you vote for them
3. Operational layer : however, you note, the good parliamentarian works for an idiot, so you can't vote the good parliamentarian unless you want an idiot prime minister
4. Strategic layer : you later decide, that it's ok to have an idiot PM, as long as there are good parliamentarians, so you vote the good parliamentarian anyway
5. Policy layer : you've always found the good parliamentarian to be an irritating bugger, so you're not actually going to vote for him ( alternatively : you don't believe that Malaysian democracy is worth your time - so you don't vote at all )
