Essayist: Politicians deserve protection from a prying press.
Conclusion
It is time to put a halt to this trivial journalism (where the press focuses on politicians' private lives).
Evidence
Politicians deserve protection from a prying press. No one wants their private lives spread across the pages of a newspaper.
The threat of being hounded by the press deters talented people form pursuing a career in politics, and it turns journalists into "character cops" who just keep hoping to find some flaw or transgression related to a politician so that they can turn it into a news story.
Evaluate / Goal
Since there are several premises put forth and since this is an EXCEPT question, there are probably too many angles to consider.
We should just head to the answers and get rid of four answers that help the author. The answer should make it sound like - this trivial journalism is bad and should be stopped - we don't want talented people to be dissuaded from politics - politicians deserve protection just like everyone else
