according to the Drum Major Institute, if you average their newly released 2007 grades with earlier ones:

Hillary Clinton:

2007. A+
      
2005. A
      
2004. B
      
2003. A

Barack Obama:

2007. A+
      
2005. C

Obama received a poor grade in 2005 for two votes. First, he voted for H.R. 6, the Energy Policy Act of 2005. The Drum Major Institute commented:

The most startling thing about this legislation is what it does not do. In the first place, the 1,700-page multi-billion dollar bill fails to help middle-class consumers squeezed by high gas and fuel costs. The rollback in public safety protections also puts middle-class families at risk, for example by exempting oil and gas companies from the provisions of the Safe Drinking Water Act when these companies inject carcinogenic chemicals into the ground. At the same time, the deregulation of public utilities exposes the middle class to a different kind of risk: stemming from increased consolidation of utilities that could raise electric rates and manipulate energy markets. What the bill does do is provide massive taxpayer subsidies - to the tune of $85.1 billion dollars - for some of the world's most profitable corporations, so that, among other things, they can drill on public land while paying the public less, ultimately leaving middle-class families to pick up a bigger share of the cost of public services. Finally, although the legislation comes at a time of overwhelming scientific evidence about the dangers of global warming and increased concern about the nation's dependence on foreign oil, it does very little to address either problem, neglecting to even increase fuel efficiency standards for cars.
