U.S. Secretary of Education Margaret Spellings was in Minnesota on Tuesday to announce a proposed pilot project for the federal No Child Left Behind law that would give 10 states more flexibility in addressing struggling schools' specific needs....
However,
Minnesota doesn't yet have enough of those schools to participate in the pilot project, prompting some to question why Spellings made the announcement here and whether it was an effort to help Sen. Norm Coleman in his reelection campaign."It certainly smells that no Democrats were invited to this event, when we already know that this administration has politicized Cabinet agencies," said Matthew Miller, a spokesman for the Democratic Senatorial Campaign Committee. "It looks like a stunt to help Norm Coleman's campaign."
