How is the best way to pick our leaders? It is a problem every democracy wrestles with. In our country, we try it two different ways.
At the federal level, we elect a president and he chooses everyone else. If one of them messes up, the president is responsible so the appointee usually is gone quickly. The result is a team effort.
At the state level, voters choose a governor, secretary of state, attorney general, auditor, treasurer, land commissioner and five corporation commissioners.
If one of them messes up, that person is responsible. The governor usually is not well acquainted with the individual. Few voters are acquainted with the individual either. They likely voted based on party line.
