Some big corporations like Coca-Cola, Kraft, and Pepsi have cut ties with a conservative group called ALEC -- the American Legislative Exchange Council. ALEC helps state lawmakers with issues like voter identification legislation, immigration, and stand-your-ground gun laws. Those legislative measures are not new to controversy, but opposition took a new tone after George Zimmerman shot and killed Florida teenager Trayvon Martin. CQ Roll Call's Janie Lorber discovered ALEC lost another big supporter this week.
