They have been affiliated with Daily Kos, but at the same time, they have a pretty good track record. They were one of the most accurate pollsters in the last election cycle, nailed the Massachusetts Senate race and were one of the few to have O'Donnell winning in Delaware.
Hello . They are usually way off and pure crap.
They were wrong about Hoffman, Christie, Burns.
Pure Dem party/Daily Koz propaganda >
They did pick odonnell but they also picked hoffman and have been way off in many other polls including Scott brown. They have a weird formula for determining party turnout. In primary turnout model odonnell race was easier. In regular elections if you estimate rats turnout 2 percent ,ore or rebus 2 percent less changes poll results significantly
