In fact, I'm all for online voter registration. It requires the exertion of effort and the physical presence of other people. And as such it is irreproducible online. Sadly, our increasingly shabby polity disgracefully fails to live up to the process that sustains it. But it's misguided to blame the mechanics of the polling place for the cynical corrosion of political discourse.
People are simply sick of the product.
The e-ing of the electoral process won't move the needle on the disaffection scale. Let us know what you think. Vote early and often.
