Rep. Adam Smith (D-Wash.) appears to be headed back to Congress for an eighth term after holding off a challenge from Pierce County Councilman Dick Muri.

With more than three-fourths of the votes in, Smith leads Muri 54 percent to 46 percent, and the Associated Press called the race for the Democratic incumbent.

The 9th district stretches from Olympia, past Tacoma and into the southern suburbs of Seattle. It has trended Democratic since it was created after the 1990 census and voted 53 percent for Sen. John Kerry in 2004 and 58 percent for President Barack Obama in 2008.

Two other federal races in Washington remain undecided. Sen. Patty Murray (D) is currently leading Republican Dino Rossi, and Rep. Rick Larsen (D) is clinging to an about 500-vote lead over John Koster, the Republican whom he beat in his first election to Congress in 2000.
