I think a lot of people are confusing the role of the president with that of the executive director and the other full-time employees we have on staff. While there are significant responsibilities that are required of the president, and there are periods of time that are highly demanding, it is nowhere near a full-time job over the course of the year. It would require the other employment to be flexible enough to accommodate those busy periods.
A couple elections ago we had a candidate who was a retired state trooper who promised to commit himself 100% to the role of USPSA president and not engage in any other outside employment. Despite having a long and distinguished track record of volunteer service to USPSA, including being a former BOD member, that candidate lost to an incumbent who was known for being pretty hands-off about the whole thing.
The right candidate is the person who is capable of efficiently mixing the USPSA president gig with his flexible outside employment or self-employment, and/or someone who is financially secure and is not especially concerned about the money. Based on the current duties of the president, I don't see any reason to raise the salary.
