Yes Aaron wasn't favourite to win last year, but you have to bear in mind that last year was the first time "vote to save" had been brought in, so bookies we're still gettin to grips with that format. They couldnt get their heads around Aaron having such a large fanbase, yet getting boo's every week. I think this year, bookies have worked out that people like Aaron and Deana can go far, and win.
This is why Deana is favourite/joint favourite with the bookies this year.
