> Getting ignorant people to cast poorly-informed votes does not help our society.
I'm not usually one to say this, but this is a very high-and-mighty way of looking at your society. In Australia, voting is mandatory for every citizen. We have just as many misinformed people, but voting is seen as a civic duty in the same way that jury duty is. If you don't show up, you get fined (though skipping jury duty has a much higher fine).
I think the jury duty comparison is quite apt, actually -- in the case of voting (depending on your voting system), most individuals have very little individual power over which way an election will go. But as a member of a jury, you have a very large amount of power over how someone else's life will go. My point is that if you believe in mandatory jury duty (which I do) then you should also view mandatory voting as being no more insane than mandatory jury duty.
I agree with the rest of what you said, but I disagree that only well-informed people should be pushed to go and vote. It should be the duty of everyone to vote, because if you don't uniformly push even misinformed or disinterested people to vote then you are providing a gap for particular parties to push their supporters to out-vote you -- which is a ridiculous problem to have in my view.
> These are not the bottleneck.
As an outsider, it seems to me that the bottleneck in the US is laws being passed to explicitly make it more onerous to vote and other various organisational aspects (difficult to do early or postal voting, election day is on a Tuesday, bosses are allowed to fire employees for going to vote, really long lines at polling places, etc).
I'll never understand why so many politicians and citizens in the US view making voting more difficult as being anything other than a move away from a democratically elected representative government.
(As an aside, in Australia we don't have any form of voter ID. You just say your name and address and whether you've voted before and then you get a ballot.)
