Education Secretary Arne Duncan's speeches on school reform and Labor Secretary Hilda Solis' interviews about falling unemployment aren't technically campaign events. But they're all about promoting the president's policies.
The campaign also has taken advantage of loopholes in federal election rules that allow Cabinet secretaries to campaign if they're appearing as private citizens, not in their official capacity.
That means Interior Secretary Ken Salazar, a former Colorado senator, frequently shows up at campaign events in his home state. U.S. Trade Representative Ron Kirk, who is black, joined a recent get-out-the-vote bus tour in North Carolina, where Obama needs big turnout from African-Americans. An email announcing Kirk's participation noted he was appearing "in his personal capacity" and urged reporters to refrain from using his official title.
