Brown's actions were driven from above and from within. Being a beneficiary of the cronyism and electoral spoils system, he naturally continued with that modus operandi.
Political appointments (supporters, party members who've earned their spurs, old school cums) should be banned. Not just heads of NASA and FEMA, but the Obama move to appoint Kerry particularly stands out. Hillary, it could be argued, had huge experience in matters of State from her years as "the other woman" in the White House. I also have to say that the Dems are apparently worse at this when it comes to SoS. It's a political plum to them, not a position where hiring is based on merit.
