Those Swing State Polls

I said the other day that swing state polls seem to be better for Obama than his national average. Yesterday, a couple more polls came out building on this trend.

PPP has Obama up 51-43 in Virginia on the same day they released a national poll showing Obama up 49-44.
SurveyUSA has Obama up 47-43 in North Carolina.
Rasmussen (which has a Republican lean) sees a tossup in Floria (Romney leads 46-45). In the same timeframe, Rasmussen released a national poll showing Romney up 48-46 though a more recent national poll from Rasmussen has Obama up 47-44.

The reason the national media does not comment much on these state level polls is twofold:

1) It is early. Much will change.
2) Most of these early polls are of registered voters, not likely voters. The reason for this is that it is impossible to get a very good read on the likely voter pool this far out from the election. Indeed, Rasmussen is the one pollster that regularly goes with a likely voter screen this early and that is one big reason why their polls have more of a Republican lean.

Those are fair caveats. But the bottom line is that this is 51 separate races, most of which (like California, New York, Kansas, and Utah) are already decided, not a national race. In the states that are not decided, Romney is in worse position than he appears to be in the national polls.

UPDATE: A Rasmussen poll in Nevada has Obama ahead 52-44.
