With Ray LaHood out as President Obama’s Secretary of Transportation, observers have been speculating on who might take the nation’s top transportation post. According to The Hill blog, the latest front-runner is standing National Transportation Safety Board (NTSB) chair Deborah Hersman, replacing LA Mayor Antonio Villaraigosa, who has said he wants to focus on his remaining time in office. Hersman has said she is not interested in the job, and according to the Hill, the NTSB responded in a statement, “Chairman Hersman’s full attention is focused on the important work of running the NTSB.”  [Via Planetizen.]
