Its all a distraction ploy. Personally I am tired of hearing of politicians affairs. People get the leaders they deserve in a democratic system. If the leaders are flawed its because the society is flawed. We can not be imperfect and of zero moral values and expect to have leaders with excellent moral values.
The mistake many people make is to presume that leaders are their moral standards - Wrong.
If you are looking for a role model look to your bible look to Jesus Christ.
Stop holding people to standards we do not live up to ourselves.
The real questions you should ask is should be about the policies and how they would improve quality of life or the economy of the nation.
