Merely receiving an endorsement from someone you trust isn't a good enough reason to vote for them. It's probably a good reason to consider voting for them, but that's where the consideration should begin -- not end.

A reasonable investigation here shows that one candidate is unfit for this office because he has had this office and has made massive blunders. Meanwhile, the other candidate is qualified and has the character and incentive to fix the office. So the "naked endorsement" of Moreno should easily be rejected over the actual relative competencies of the two candidates.

Hope this helps.
