Both unions have said they like the idea of Obama choosing a governor or former governor. There are many to choose from, including Kansas’ Kathleen Sebelius, whose name has been floated for several Cabinet posts, and former Gov. Roy Barnes of Georgia.
The names of former Mississippi Govs. Ray Mabus and Ronnie Musgrove have also surfaced; several people said Musgrove has talked to Democratic senators about the job, but he did not return a call from The Associated Press.
The unions backed Obama’s rival, Hillary Rodham Clinton, in the primary, but they spent millions of dollars supporting Obama in the general election against Republican Sen. John McCain.
