After a not-so-good performance of "Blue Suede Shoes," Aaron remains at the bottom of our power rankings. We suppose the bottom is better than being voted off, which is probably what he deserved this week.

His performance of "In the Ghetto" helped him bounce back after his near-elimination, but Michael still doesn't have much support among our voters. If Big Mike can continue to sing as well as he did last week and leave the shtick behind, he'll be able to stick around a while longer.

Thanks to teen girls everywhere, Tim survived several bad performances on his way to delivering one of his best yet. His take on Elvis' "Can't Help Falling in Love" wasn't a revelation, but if he can survive when he's bad, how far can he go by being OK?

Casey's "Lawdy Miss Clawdy" felt like a step backward after his star-making performance the previous week. But he still has enough support among our voters to stay right in the middle of the pack.

Siobhan's "Suspicious Minds" — screechy high notes and all — didn't earn big praise from the judges, but it doesn't seem to matter at this point. To be fair, she at least provides some diversity among all the guitar strummers still left in the competition.

Lee probably fared as well as anyone did during Elvis Week, as his version of "A Little Less Conversation" sounded the most relevant. He remains a bit of a bore to watch on stage, but at this point we don't see anyone but him giving Crystal a run for her money.

Crystal was once again great on "Saved," and unlike Lee, her personality is keeping up with her talent. As long as she doesn't give up on herself, it's hers to lose.
