Doing the Census
As with any huge undertaking, the census requires years of planning, but preparations have been systematically sidetracked during the Bush years. The most plausible explanation, beyond incompetence, is that the administration aimed to make it even more difficult than usual to count hard-to-count groups, like minorities, immigrants and the poor, who tilt Democratic. Their numbers, if accurately gauged, could reshape electoral maps.
The White House, with the early support of a Republican-led Congress, shortchanged and delayed financing for the Census Bureau. The administration left top bureau positions unfilled for long stretches and allowed political judgment to dominate bureau management, which damaged morale and impaired performance.
I really think they're just incompetent, I don't think it's intentional.
