In all honesty I don't think any of them will. Even though i'm sure a bunch of people will vote 'Callum', I won't vote for 'Dexter' just for the sake of a negatively geared poll. I think Dexter is too clever and calculated to make a third mistake and he'll be on his best behavior now that he's gotten two warnings. Other than that, I don't think any of the housemates are outrageous enough to risk being ejected. But then again, we all thought Daley was a bore until he was dramatically ejected too, so who knows!
