Wow... Singer/songwriter - you make it sound as if the singer/songwriter is lame.
I have got to respectfully disagree with you. Adam is an actor who happens to be able to sing(very well). He is NOT a musician, he can't arrange songs and most likely he can't write. He is trained in theater and no doubt is good at performing a part (me thinks the yelp at the end of the results show this week may have been a little over acted). Yes he will be a sensation around the world, although I don't think it will be all for his singing. I think it will be for his acting and looks. Kinda like Prince or some of those crazy people you see on the show. These people are all about persona and performing, not about singing a good song. And yes Prince and the others are sucessful, but if you look at them you can see the it is all about "performing" not about singing or writing songs (at least not anything memorable).
But that is not to say that Adam won't be successful. I am sure he will, but it will not be the same sucess as Kris. Kris has longevity. Anyone who knows a "singer/songwriter" knows that these people live music. It is the thing that makes them who they are. That is what I see in Kris. Yes he is a "simple" singer/songwriter but guess what those are the people who write the songs Adam will perform. Kris can interpret a song, play the heck out of it on multiple instruments and can sing it to the heavens. He makes people feel songs, because he feels them when he sings it. Adam will entertain people. Both are valuable.
While I agree that people should vote for who they like and I know most Adam fans are hoping that Danny fans will not vote this week, but the truth is that many people see that Kris is the next best thing to Danny. I suspect that if it had been a Kris/Danny finale you would be voting for Kris even though you think he is just a typical, nasal voice, singer/songwriter!

Or at least many Adam fans would because they see Danny as the opposite of Adam.
Lets be honest. Kris and Adam are in the finals because they both have talents. If Danny had been in there that would have been the case also. I actually believe that one of the reasons Kris is there is because Adam fans voted against Danny. So you can be judgemental of people for this, but I believe that is how Danny got booted. After Simon did his plea (which only confirms that Idol knew that Adam's numbers were lower than everyone thinks) most Adam fans probably knew that Adam was in and voted for Kris some to get Danny knocked out. IT may end up backfiring on them though. Because Kris is the "whole package" when you are talking about a singer. He doesn't need to act to be in the final two. He did what he is best at....Sing and play music. These are the people who make it the music industry. Adam will make it in the Broadway/Hollywood industry. I suspect he simply will falter without the stage to perform on. But then again I could be wrong, Kellie Pickler made it and she can't act or sing.
Sorry that is how I see it.
