The mass media have a powerful influence on politics. They shape the perceptions of the political world that average people and political leaders hold. These perceptions become the basis for political beliefs and actions. The mass media are particularly important during periods of rapid political changes, during elections, and in times of war and political violence. That is why political leaders try hardest during such times to control what the news covers.
This can be very beneficial to some candidates and detrimental to others. It is important for politicians to have a clean slate, but since they are only human its not very likely. It seems that the public takes what they learn and the have to choose the lesser of two evils. I believe people have to consider that these politicians make mistakes in their personal life, but that it shouldn't affect the professional part of their job.
