There is an appropriate and authentic protocol for issuing endorsements. Typically, candidates may appear in person before the endorser (sometimes, an editorial board) to answer questions. Occasionally, an endorsement decision may take the form of a closed-door debate among the candidates. In many cases, candidates submit answers to lengthy questionnaires prepared by the endorser. After vetting all the candidates, the endorsement decision is then published.
The idea behind the endorsement, is that an endorser has vetted all the candidates on the ballot and selected the best candidate for the position.
Without this discipline, a candidate’s list of endorsers is merely a publication of his Facebook friends list.
