The press reports on political campaigns these days as if they were chess games.
Conclusion (it is clear that)
Campaign advisors should stay out of the limelight so that the press can report on the most revealing positions on substantive issues the candidates have taken.
Evidence
The press currently treats campaigns like chess matches between advisors, ignoring substantive policy issues. Voters lose because they need substantive information to make informed decisions but are getting only process coverage.
Evaluate
Because the conclusion is a recommendation ("should"), we could articulate a Missing Idea by citing the missing "should" rule that gets the author to her conclusion.
Reporting on the chess game rather than the substantive policy issues is . Since our author is saying that the press should stop reporting on the chess game rather than substantive policy issues, she's assuming that .
If we wanted to go down the road of thinking of Potential Objections, we might react to the wording .
Who said the advisors were in any way pressuring the press to report on them rather than on substantive issues. The author's conclusion makes it sound like advisors are intentionally seeking press coverage, but it's possible the press just chooses to cover the campaign because it gets more clicks than covering the issues does.
Goal
It's hard to know what to predict here. Maybe it'll be testing a missing "should" rule. Maybe it will be ruling out some sort of objection.
