The race gained national attention for its legal twists and extremely close finish, among the closest political races in United States election history. Republican Dino Rossi was declared the winner in the initial automated count and again in a subsequent automated recount, but after a second recount done by hand, Democrat Christine Gregoire took the lead by a margin of 129 votes.
