It's the best chance for reform we've had in a long time.
We know a lot more about election theory and other things than we did in the 1850s. It would be good to get a chance to implement some of these new ideas (such as ranked preference voting) in areas open to them (such as the Silicon Valley). Other areas might want to stick with more traditional voting (for example). But each area would be much more in control of its own future.
