Here's something I hadn't thought much about: Many of President Obama's cabinet picks still await confirmation by the Senate. So, who's running the show in the meantime? ProPublica.org found out:
Frequently, the acting position falls to civil servants at their respective departments, non-partisan types who have toiled for years or decades in relative obscurity. William Burns, acting secretary of state until Hillary Clinton took over, is a career Foreign Service officer. Otto Wolf, acting secretary of commerce, was chief financial officer of the department under the Bush administration.
