Pledging to vote can help a candidate all of the following ways EXCEPT: A. raising the candidate’s poll numbers B. making the candidate appear weaker C. encouraging others to vote for candidate D. increasing the candidate’s media visibility
Pledging to vote for a candidate would be only positive for this candidate: so we have to choose an option that would not be a positive outcome for this candidate.
Such an option is "making the candidate appear weaker" and indeed, pledging to vote for a candidate would not make this candidate appear weaker. (answer B)
