Do they feel the rules don't apply to them? Or are they in over their heads?
Were they not prepared? Or do they just not care?
I don't know the answers to these questions, but they're fair questions that deserve to be answered. Obviously the FEC feels that the questions deserve to be answered too.
Whatever the correct answer may be, the fact that the questions are being repeatedly asked doesn't reflect very well on the candidate's ability to choose responsible and capable individuals, or his ability to delegate and take charge, or his ability to prioritize and accept responsibility, or his ability to quickly address and resolve problems.
