The League of Conservation voters recently released its National Environmental Scorecard, which rates members of Congress based on how often their votes supported environmental protection measures. Personally, I'm a sucker for credible reports that hold members of Congress accountable for their actions.

Five representatives in Congress from Michigan and both U.S. Senators earned a score of 85 percent or greater on the 2012 Scorecard (meaning they voted in favor of environmental protection measures 85 percent of the time).
