Interesting chart. From it we could assume that the bottom four will drop out in the next four weeks; then McPhee and Daughtry will cancel each other out; and the two biggies left standing at the end will be Taylor and Kellie.
I don't have any confidence in that chart.
The only biggies I've seen (and heard) in the competition have been Chris, Elliot and Taylor. McPhee might be a contender too, but she's running out of time.
Nothing Pickler has done has impressed me.
