This argument from authority is hardly convincing. As Seth Tillman notes This precise issue was addressed by the Supreme Court in Marbury v. Madison. "Chief Justice Marshall wrote that the President's nominating a person to an office is 'completely voluntary,' not a duty, much less a constitutional duty."
Geez. Marbury v. Madison is only the earliest Supreme Court case they still talk about, and Seth has to re-edumicate the greatest legal minds of our time on it.
All is lost. Or nearly so. Bless you, Seth. Keep scrappin'. There's a constitution in there somewhere.
