Gary Langer of ABC News reports that 9% of registered voters have voted already, with Bush leading 51% to 47%. Langer notes that this does not necessarily mean Bush is “winning,” however, as a four point lead is within the margin of error. He also notes that early voters tend to be a bit more Republican than the overall electorate, suggesting that even if the number were statistically significant, a slight lead by a Republican President would not necessarily translate into a lead among the electorate at large.
Langer notes that early voters are located disproportionally in the western states, but does not elaborate further as to how this may skew the overall result. The one state he mentions by name, Oregon, should be the most over-represented of all, as all Oregon voting is done by mail. Next in line would be California, the nation’s most populous state, which allows voters to register as “permanent absentees.” Both states lean heavily Democratic, so to the extent Bush is even slightly ahead among the early-birds there, that really does mean something. Expect similar results from Washington, but opposite results from Arizona, Nevada, Utah and the other western states hardly anyone lives in (and I mean that in a good way).
Bottom line: show me a list of the 28 states that allow early voting, with a breakdown of what percentage of the electorate has already voted in each, and I’ll tell you whether Bush, Kerry or the cat is winning. Based on ABC’s generalities, it’s impossible to tell.
