Consultant: The mayor shouldn’t adopt her rival’s controversial proposal for solving the city’s budget problem.
Conclusion (shouldn't = opinion)
The mayor shouldn't adopt her rival's controversial proposal for solving the city's budget problem.
Evidence
If she adopts the proposal and it succeeds, she'll potentially increase her rival's credibility.
If she adopts the proposal and it fails, she'll get blamed for endorsing a crazy idea.
Evaluate
Structurally, it feels like the the argument is saying:
CONC: we shouldn't do X.
EVID: If X succeeds, something bad happens to us. If X fails, something bad happens to us.
Goal
Look for a conclusion saying "we shouldn't do something", and premises (probably both conditional) that feel like "damned if we do, damned if we don't".
