It does seem as though they've learned that staffing is the biggest challenge of the first hundred days. As Clay Johnson, former deputy chief-of-staff in George W. Bush's first administration, kept saying last summer, "Personnel, personnel, personnel, get that house in order!" And they have taken that message seriously. There's been, for example, a pretty short amount of time between announcing someone and filing their paperwork.
And this has paid off in 63 Senate confirmations and the likelihood of breaking Reagan's first 100 days record of 83, maybe even what everyone says is impossible: 100 confirmations by day 100. This is a huge lead in comparison with George W. Bush, and it wasn't as if the Bush camp was unprepared. In 2001, they hit the ground running, launching the most successful transition of the post-WWII era.
Are there particular challenges Obama faces in continuing to staff the federal government?
Two major ones. The first is specific to him. The president campaigned on and set out to accomplish a transformation of the Washington community and how it relates to governing. This includes a set of restrictions on prior lobbying experience. Making these changes is not an easy thing to accomplish if you want to garner enough people with experience.
The second is typical of all transitions. Finding a balance between loyalty to "them that brung you" through a grueling presidential campaign and reliance on those that you need to take on the more complicated job of governing. That is where the plethora of Clintonites in the Obama camp has come from.
The scale of the American executive is gargantuan by comparison with any other organization. To break it down, there are 8,100 positions that the president could be involved in selecting. Many of these, however, are not policy positions. Only 1141 are sufficiently important enough to warrant the advice and consent of the US Senate. But even in this group, many do not constitute positions with central policy making responsibilities. 542 carry enough awesome responsibility to be considered "important" to governing, but now we are talking about a very rarefied group. 348 of those positions are in the big Cabinet agencies. The others are spread throughout the executive in groups like the Council of Economic Advisors, the Board of the Federal Reserve, and the EPA.
When presidents complain that the Senate is dragging its feet, should we believe them?
Dragging one's feet for one person is exercising prudence on policies that matter to others. There is a constitutional invitation to struggle built into the checks and balances system. We often focus too much attention on the few cases where this struggle might bubble to the surface as a controversy. Right now, the Senate on average is taking about 3 weeks to decide on Obama nominations. Twenty-one days is hardly dragging one's feet.
