Here in Oregon we vote by the US postal system. They send you a Voter's Guide, and a few days later a ballot, and you fill it out and sent it back. I sent mine back this morning.
Sounds easy and wonderful. But I don't like it.
Maybe I'm old-fashioned, but I like going to the polling booths. It makes you feel like a citizen.
OK, it was especially fun in New Hampshire where, during a presidential-election year, all the polling places are plastered by activists and media and you have to wade through them to get to the booths. You feel like your vote really mattered.
But beyond that, I liked having to go to a community center someplace and showing my face. Not that anyone especially knew me, or that I knew them (though many people did know their neighbors). But you got a sense of community that is missing with vote-by-mail.
With VBM you feel very much on your own. You feel completely alone. And that's just not how a democracy should feel. We have far too little sense of community these days anyhow. VBM just makes it worse, not better.
