I am still confused. Can you expound some more?
In the most simple terms:
King County went 70% Obama and 28% McCain in 2008. So far, 16.5% of the 2008 early voters showed back up to vote.
Franklin County went 37% Obama and 61% McCain in 2008. So far, 26.4% of the 2008 early voters showed back up to vote.
King County is very Dem heavy. They aren’t showing up to vote at the rate that the Rep-heavy county is. This appears to be a trend across all of the Washington State numbers.
