In wooing federal employee votes on the eve of the election, Barack Obama wrote a series of letters to workers that offer detailed descriptions of how he intends to add muscle to specific government programs, give new power to bureaucrats and roll back some Bush administration policies.

The letters describe Obama's intention to scale back on contracts to private firms doing government work, to remove censorship from scientific research, and to champion tougher industry regulation to protect workers and the environment. He made it clear that the Department of Housing and Urban Development would have an enhanced role in restoring public confidence in the housing market, shaken because of the ongoing mortgage crisis.
