2009 Dally M medal winner?

Many people believe that Jaryd Hayne will be this years recipient of the Dally M medal and he has played some amazing football this year. Thurston however held a huge lead on Hayne at the close of votes, 12 points the difference at 20 and 8 respectively. I also believe he has played some of his better football after round 16. Is that lead insurmountable? can anyone else stop these two? or will Thurston take yet another Dally M Medal?
