To further clarify, Washington state doesn’t provide breakdown of D or R registration, just the raw early vote totals by county (and not by every county). So, what my number crunching shows is the higher the percentage of 2010 early vote totals in a county, the higher the turnout. And by and large, the counties that McCain won, are turning out bigger percentages of voters over 2008.
Dumb question - since Washington is a mail-it-in state now, how do we know any early vote turnout numbers?
