The three current presidential hopefuls with experience as state governors have records on education that offer voters an unusually detailed preview of what the nation's schools might expect if any of the three should win the White House next year. Those candidates--New Mexico Governor Bill Richardson, on the Democratic side, and former Governors Mike Huckabee of Arkansas and Mitt Romney of Massachusetts, in the Republican field--are still working to refine their positions on national education policy. But their state experience already offers clues to what their priorities might be and how they might work with Congress to get their platforms accomplished, said Jacob E. Adams Jr., an education professor who studies education governance at Claremont Graduate University in California. Despite ideological differences, the three gubernatorial veterans in the 2008 race share some experiences in dealing with education. Each served at a time when states were in the throes of implementing the testing and sanctions requirements of the federal No Child Left Behind Act, signed into law in 2002, while grappling with the effects of the economic slowdown at the start of the decade. And for all of them, echoes of their time in the governors' mansions can be heard on the campaign trail.
