Three solid wins for Obama. Check out the lop-sided victory in Washington. I can find only one jurisdiction that Clinton won: Douglas county, named after Lincoln's debate opponent. The landslide in Washington is probably because a lot of people had experiences like this one:

I live in a fairly liberal and affluent exurban community outside Seattle. I participated in our statewide Democratic caucus today. It was the first time in 24 years that I attended one of these events. I was not alone, as turnout was estimated at triple the prior cycle. My precinct was composed of mostly middle aged whites. A handful of African-Americans were there.

Obama received 80% of the vote and grabbed all the delegates except for one non-committed. Clinton did not secure enough votes for a single delegate to be sent to the next level. The few Clinton voters were older (60+) women who are either single issue voters of old Democratic times, or supporting Clinton because she is a woman. I feel bad for them because that first serious woman candidate has been Clinton.

Should we call a landslide of white votes for a black candidate an avalanche?
