Citizens in Charge Foundation -- led by Paul Jacob, best known as leader of the term limits movement and as a member of the now free Oklahoma 3 -- is building what, in my experience, appears to be the first truly national organizing network around initiative and referendum.

In an email, Citizens in Charge says it now has 13 "Citizen State Coordinators" (the goal is to have someone in every state) to work to defend and expand initiative and referendum rights in the states. More about this here. Whatever you think of Jacob's politics, this is a smart move  that will encourage more thinking about direct democracy and, one hopes, more civic engagement.
