Bell, Cherry, Republican... Nudge

Recently word came out that there is a critical flaw in the machines used as electronic voting booths in some US elections. It is important that this technology is done right and not just rushed into — as with the postal voting fiasco in some of last year's elections in the UK. What is more worrying is that these voting machines are subject to far less rigorous controls than slot machines. So which is more important: gambling or democracy? I guess we can look at that in a different way: which is a bigger source of tax revenues and which is an expensive overhead?
