Well, you can’t nominate somebody who doesn’t want the job in the first place.
And good people, for the most part, don’t want to get involved with the Government these days.
This is true. I suspect it is true largely because every appointment tends to become politicized and picked apart by hostile media who have nothing better to do with their time.
One’s entire life after age 12 becomes fodder for discussion on CNN. Some very qualified people may choose not to put their spouses, their family members through such artificial inquisitions. No one wants all their ‘dirty laundry’ hung out for public scrutiny, even if you’ve lead the most boring life in history. It’s your private life. I hope this changes within the next decade or so.
