I think Dani has a great voice, but her other qualities (acting, movement, stage presence) are lacking. I think she's just not ready for this level of performance yet. I know she has a lot of online support with Facebook and Twitter, but I really don't see her lasting much longer because she doesn't seem to make a lasting impression with her performances.
I think that's one big reason people didn't vote for her in this poll. She was good, yes, but others stood out more.
My favorite this week was Danielle, followed by Stephanie, and then Steph.
