Walker, Fiscal Ranger

from the gao site:

Gene L. Dodaro became Acting Comptroller General of the U.S. Government Accountability Office on March 13, 2008, succeeding David M. Walker, who appointed him upon resigning. Mr. Dodaro will serve in this position until the President nominates and the Senate confirms a successor from a list of candidates proposed by the Congress.

In a GAO career dating back more than 30 years, Mr. Dodaro has held a number of key positions at GAO. For the last 9 years, Mr. Dodaro has served as the Chief Operating Officer, the number two leadership position in the agency, assisting the Comptroller General in providing leadership and vision for GAO

Who will be replacing Walker? A 15-year Bush appointee?
