Believe me, I share your frustration. But I don't think that would work any better. Then you'd have groups thinking it'd be funny to vote off the best singer instead of those who think it's funny to keep around the worst.

I think someone else suggested that America should pick the bottom 2 or 3, and then the judges should decide out of that group who should go home. That might work better. But since Sanjaya has yet to be in the bottom 2 or 3, it's obviously still not perfect.
I'm another Jordin & Melinda fan. I think they're both great, and would be happy to see either of them win. I'd give the nod to Jordin if I could, since she hasn't had the years of experience Melinda has, and yet she's still fantastic.
