Blair Levin, who had worked on Obama’s transition team, was a senior adviser to Genachowski and helped craft the agency’s National Broadband Plan. During the Clinton administration, he served two tours at the FCC as chief of staff to Reed Hundt.

But Levin may face steep opposition from the broadcast industry, who fought with him over using their airwaves for a proposed auction to wireless companies.

Jessica Rosenworcel, a Democratic FCC member, is a freshman commissioner but has telecom chops. She served for years on the Senate Commerce Committee as senior staffer on telecom issues for Sen. John D. Rockefeller (D-W.Va.), whose support should smooth any confirmation concerns.

But Rosenworcel would find it hard to land the top seat at the FCC before Democratic commissioner Mignon Clyburn, daughter of assistant House Minority leader James Clyburn.

Lawrence E. Strickling, the highly regarded assistant secretary of Commerce for Communications and Information and head of the National Telecommunications and Information Administration, is another possibility.

He also served on the president’s 2008 transition team and helped on the 2008 campaign. The Chicago native is seen as close to a number of White House officials.
