It's almost all down to the public vote by now. And not much to do with how popular Ashley really is.
It is almost impossible for the leader after Saturday to be in the bottom two. Ashley was middling position, and everyone knows she will be in the final, because she will beat anyone in the dance off. So no one voted for her. Lauren is the worst dancer left, but is still under marked, imo, especially compared to Graham. But AJ, the girls who've been attracted to vote by Jow love him too, so Lauren gets saved.
