Nethercut must have lost by more votes than are still outstanding, same with the Presidential race. I guess..... good question though. 36 of 39 counties in WA went for Bush, and he still lost the state. Time to break King County up........for many reasons!
CNN updates their info fairly often - the numbers continue to change - check it out. Looks like although Nethercut is a lot farther behind than Rossi, it is concievable that he could still be the winner in WA - and so could Bush!
