Why do we worry so much about voter turnout? A 58% voter turnout is a statistically significant sampling of the population; aren't we getting a pretty accurate measurement of the actual vote with that high of voter turnout?
Now if voter turnout is skewed, then that's a problem worth talking about. But with how much time and effort it takes to vote, it seems like such a waste of time with how we do it today.
We could get the same results with much less effort if we made it work like jury duty; at each election we select 10% of the population at random and it's their job to actually do the research and go to the work of voting (research candidates, wait 3 hours at the ballot box, etc), and the remaining 90% of us get to go watch a movie or something that day.
