A spokesman for U.S. Transportation Sec. Mary Peters told PolitickerAZ.com that Peters is not currently thinking about staying at her post under a John McCain administration, nor about a gubernatorial run, as reported in CQPolitics.com:

There is growing speculation McCain would ask his fellow Arizonan to stay on at least through the first half of next year, after which she wants to return to Phoenix to start her 2010 campaign for governor. In the Cabinet only two years, she appears to want more time to push her ideas, which include replacing the federal gasoline tax with a tax on drivers based either on how far they go or when they’re on the road.

Peters, who is the former director of the Arizona Department of Transportation, considered a run for Arizona governor in 2006, and is rumored to be taking a look at throwing her hat in the ring in 2010.  

However, Brian Turmail, spokesman for the U.S. Department of Transportation, said of CQPolitics.com report, "you can put that up to a speculative piece."

"It's a Washington parlor game," said Turmail. "You're going to be seeing a bunch of these pieces between now and the election."

Asked if there was any indication that she would stay on as transportation secretary, or run for governor of Arizona, Turmail's answer was boilerplate.

"Her answer is that she is focused on serving the American people and trying to the best possible job at the Department of Transportation. After that she wants to go home and bounce grandbabies on her knee."
