There could be no greater examples of the diversity of the 2016 Republican presidential field than the dueling announcements of Ben Carson and Carly Fiorina Monday morning.

Carson, the only black candidate in the race, and Fiorina, the only woman, are also the only two candidates who have never held public office before. Each is working to turn what some would call a gap in their resumes into a strength by attacking what they call the “political class” — that is, office-seekers other than themselves.
