How can he Rassmusen and other pollsters predict the turnout in the Presidential elections this year? Being accurate in a certain elections does not mean that he is going to be accurate in the next. Rasmussen was really bad in 2000 where Zogby was right and the opposite happened in 2004.
Rasmussen acknowledged errors and changed his methodology for 2004.. Zogby was experimenting with an internet-based polling system in 2004.
