So, really, these polls have little to no relation as to the outcome of the election due to the fact that each state is its own mini-election? So if, say, in Florida it is close - it could be a landslide in the polls in New Hampshire for Obama - however it is reported as generally being close?
Not quite. The national polls and the state polls are related. No one is going to win a moderate state like New Hampshire by a landslide margin unless the national race is also lopsided.
When Obama won big in 2008, the closest states were places like Indiana, Missouri, and North Carolina -- all of which are solidly in Romney's column this time. (NC is a rapidly changing state, and will probably be a swing state by 2020; the other two are solidly Republican, and were only in play in 2008 because McCain got trounced nationally.)
