WASHINGTON (AP) — Using stimulus dollars as bait, President Barack Obama is coaxing states to rewrite education laws and cut deals with unions as they compete for $5 billion in school reform grants, the most money a president has ever promised for overhauling schools. And it may end up going to only a few states.In Wisconsin, where Obama will visit Wednesday, lawmakers are poised to change a law to boost their state’s chances. Nine other states have taken similar steps.
