Going forward, I think we the people need to look at how we register to vote. Maybe voters should be required to re-register? I have to renew my drivers license every few years and other licenses/permits I have. Why not voter registration? I have to register my motor vehicles every year and my dog. Why not my voter status? I suppose people would say that is too much like voter ID (I'm a supporter) and requiring re-registration would somehow disenfranchise someone.
With every passing election I find myself leaning more and more to the concept of sortition. Better to be ruled by random people picked from a phone book...
