It may be a no-brainer that Barack Obama looks like he is going to carry Washington State on election night. The problem is that the national media maybe projecting him as the winner based on exit polls from East coast States like Virginia and North Carolina long before the polls have closed here.
The Governor's race between Gregoire and Rossi and other important down ticket races remain close and could be further affected by voters on the West coast deciding not to vote because Obama has already been projected to have won the Presidency at shortly after 4pm Pacific Time.
Here is a quote from Votemaster that makes the point.
"On a closely related topic, on election evening 2004, the battle went on for hours. In 2000, it went on for 36 days. That makes for great television. What happens if it is all over at 7 P.M. Eastern Time on election night? That is when the polls close in Virginia. If the Virginia exit polls, which are likely to be announced at 7:01 P.M., show a blowout for Obama, all the pundits will realize that the show is over, as there is no plausible way for McCain to get to 270 electoral votes without Virginia. Ditto North Carolina, where the polls close at 7:30 P.M. Are the anchors and experts all supposed to pretend they don't know what is going on? But if they call the election at 4:01 P.M. Pacific Time, millions of people won't bother to vote. Clearly they have a problem. If millions of people in the Midwest and West don't vote--especially people who were planning to vote for the loser, it could affect large numbers of downticket races."
