IMO, Katherine has caught "Kellie Pickler-itis", where the contestant does a better job in the taped-with-celebrity-coach rehearsal and then goes down in flames in the actual performance. Yes, she's appealing, yes she has a good voice but she just doesn't bring it on performance night.
Heh, I always just LOVE it when Randy says a contestant got "pitchy" in a performance. That's just his way of saying that their rendition stunk up the place.
Chris might not have given the best overall performance last night, but it would border on criminal if he got sent home, similar to when Mandisa was voted off. The thought that occurred to me is that some fans might be voting for the person that they think their actual favorite would do better against...for instance voting FOR Katherine so Chris wouldn't go any further, kind of similar to "Survivor" where you pick off your strongest competition so you'll stand a better chance.
agnes!
