If you're in a Super Tuesday state, then, to borrow from Robert Heinlein -- there may be nothing you want to vote for, but there's sure to be something worth voting against.
I'm voting for Hillary Clinton, which, given my distaste for her husband, is something of a surprise to me -- but I'd be perfectly happy with Barack Obama, so no problems there, regardless of what happens. I have a post coming about how and why I ceased being able to vote Republican. I used to occasionally (though I always voted Democratic more often), but over the last decade I simply can't bring myself to cast a vote for Republican candidates. The last Republican I recall voting for was Dick Riordan for Mayor of Los Angeles -- who offered me a job once, so there's that, but I didn't vote for him in when he ran for his first term, so there's that too. But he did a very good job as mayor, and a decade or so back, whenever he ran for his second term, I was still willing to cross the aisle to vote for the right candidate. Seems like a long time ago.
But regardless of how you feel about my politics, if you're able to vote today, do. Encourage others to vote. There's not much these days that my conservative friends and I really agree upon ... but if you're left, right, center, or off on some axis all your own (and good for you if so) ... this is one of them. Participate. It pays off, at least in the long term.
