Not everyone has the intelligence to vote and governments use this to come up with sound bites / catchy slogans to convince the dim witted to vote for them.
Im yet to meet a campainer who convinced me to vote for them, so until that happens I wont vote. I will vote for none of the above if it was an option and if the winning government had to win by a large PR majority.
Even in my life time governments have constantly gone back on promises made in elections, or decided to do something the majority didnt want ie. War in Iraqi, referendums etc etc – this is a reason many are apathetic and dissalusioned.
Sort this out and more would vote, but I really dont think everyone is engaged enough or educated enough to make voting choices that affect all of us.
For example, when you go to your doctor you dont also get the opinion of your local priest / witchdoctor / homeopathy person. You pick the one person best educate to make that importan choice. We should do this with choosing our governments.
