An influential assemblage of left-leaning policy experts and a coalition of 30 environmental organizations have weighed in with their vision for the Obama administration, adding to the burden of expectations facing the president-elect from Democratic interest groups.

The Center for American Progress, a liberal research group founded in 2003, issued a 657-page "progressive blueprint for the 44th president" that emphasizes the need for "green jobs," universal health care and tax reform. The hefty tome, its authors said, is meant not only as an aid for Obama but as a benchmark to gauge his administration. The environmental groups' agenda, sent late Tuesday to Carol Browner, a key member of Obama's transition team, was shorter but equally ambitious, outlining policies to slash greenhouse gas emissions and revamp the transportation infrastructure and electricity grid.
