I noticed a pattern right away

Kevin Drum summarizes the qualifications of the last four heads of FEMA. He quotes one line of a Sesame Street song as a hint to the pattern you're supposed to pick up. Here's the whole verse:

One of these things is not like the others,
One of these things just doesn't belong,
Can you tell which thing is not like the others
By the time I finish my song?

The headlines from Kevin's rundown. The full post is a must-read. The job is to coordinate the nation's emergency services, so some experience in that would be cool.

1990-1992: Wallace Stickney, a close friend and former next door neighbor of White House Chief of Staff John Sununu.

1993-2000: James Lee Witt, Director of the Arkansas Office of Emergency Services.

2001-2002: Joe Allbaugh, National Campaign Manager for Bush-Cheney 2000, and the guy who helped Karen Hughes sanitize Shrub's Texas Air National Guard files.

2003-Present: Michael Brown, Commissioner of Judges and Stewards for the International Arabian Horse Association, and Allbaugh's college roommate.

Connect the dots.
