Should we worry about politicians private lives?

I heard a NSW Greens senator on radio 702 yesterday commenting on the Della Bosca affair. She dragged out the old line that a politicians private life has nothing do with how they perform their public duties and that it's none of our business what goes on behind closed doors.

But the Sydney Morning Herald today quoted the woman involved in the affair (Kate) as saying: ''If he is capable of lying to his wife and children … why wouldn't he do that in other aspects of his career?''

The logic is inescapable!
