Who will go: Katharine was in the bottom two last week, but that seemed like a fluke and she was solid this week. Ace Young or Bucky Covington appear to be next in line, but both actually had a decent week. Mandisa's never even been in the bottom three, but she seems to have lost her luster. Based on singing, Kellie Pickler should be the one to go, but Elliott Yamin is forgettable. It's anyone's guess.
