I'm late coming into this season, but in coming in late sometimes, you get some different perspectives.
One is that I can see that this clean-cut kid is enormously popular -first and foremost popular.
With American Idol that is always important (cough, cough Carrie Underwood)
Next, just like Carrie Underwood everything he sings is going to sound country. He will give it an honest intention and approach, but it will still be country because just like Carrie, he is country all the way. As such, he could ride this thing all the way through just like she did straight into Nashville.
Would that be a bad thing for AI?
He is Country which is not typical for AI, but then so was Carrie, and she has been by far their biggest winner. They want a winner....
Regardless, of whether he wins AI or not, this kid is going straight to Nashville as soon as he is off this show by the first means of available transport.
I don't even listen to country music except when I am with my brother, but I have this one figured out!

He is loaded with charisma, and that deep voice is a gotcha.
