Still in Iowa

I usually pop a hammy springing up to agree with Sully, but this post left me wondrin. Yes, we all love to beat up on the Tog Dog, and Hillary of course is a Top Dog. She's an easy target to pile on when she loses something, whether she deserves it or not. And believe me, she's not getting my vote. But my question is, is her email correct? IS the Iowa caucus designed thusly, for "real" Democrats only? I mean, one thing I've discovered recently is that nobody really knows or understands what the hell the Iowa caucus even is or what it means. I know I don't. But I don't like Sullivan's tone here - the ol' middle finger to the establishment seems too easy here, too rote. A tone of getting what we want over getting what's right right. Dunno. Leaves me a lil not too proud to be a liberal right now.
