Arkansas - Tie - Rasmussen Reports

[Reds4]

Anyone have any input on why Rasmussen nationally keeps showing the race a tie.. kerry will go up by 3 or 4, then bush come even, then the same thing will happen the other way.. but Kerry seems to be polling really well in all the state polls. Arkansas- a tie, Wisconsin- up 8, Ohio up 4, Iowa up 10, and so on... From the polling rasmussen is putting out it seems he is saying this will be a national dead heat but the electoral college will go to Kerry by a lot. Any input on why the disconnect between the state and national polls of rasmussen?
