You have an important job opening that you need to fill. Failure of this person in this position has HUGE ramifications. The stakes are high. Which way would you go for your selection:
1. Someone who has a personal recommendation from someone you highly trust, but who has a resume that you consider run-of-the-mill.
2. Someone with a stellar resume, but otherwise know absolutely nothing about.
Think about this and pick one, and only one, for your important job opening. There is no "right" answer.
Now look at how you picked and your reaction to the Miers nomination. Did you choose one method but want another method for the nomination? If different, why? Would you pick one method if YOU were President, but want another if you were just an average citizen? Would you use different methods for different positions?
