So there will be 25 to 30 minutes between the third place finisher is announced and the end of voting altogether.

No doubt, Sam will be leading at this point. But will have a big enough lead? ]
He seems to have the casual voter but the majority will be anti Ginxster not really Pro-Sam. These voters will vote maybe once or twice for him.

It is likely that the fight to get the second spot in the final 2 will be between Dexter and Gina. At the moment, they are splitting the Ginxster vote but whoever loses this battle it is almost certain that they will switch in large numbers to the other member of Ginxster. It also likely that they will vote numerous times.

If the producers give enough time for this process to play out, and do not close the phone lines too early, it is likely that the surviving member of Ginxster will win!
