We’re welcoming a couple of new guest bloggers to Duck. Jay Ulfelder, who blogs at Dart Throwing Chimps, is a political scientist who does excellent work forecasting regime survival and change, democratization, and violent conflict. And Erica Chenoweth from Wesleyan University will be posting as Rational Insurgent — also the name of her blog. She’s done some amazing work on terrorism and most recently on civil resistance and non-violent conflict. A very warm welcome to both!
