Any campaign, be it Presidential, Senatorial, Congressional, State, or Civic, or Parliamentary, has a number of staff positions. Some of these are key, some of those are found more on some levels of campaign than others, and some are over-rated. Rate 'em.
P.S. The word "Boys" is deliberately chosen. The key campaign staff ride on the campaign bus, plane etc. and regardless of gender, they call themselves boys.
