Like many advocacy groups, the NAACP evaluates members of Congress based on their voting records around a certain agenda. The NAACP has been grading Congress on what it calls the "bread and butter" civil rights agenda since 1914.
All Senate Republicans received a grade of "F" on the report card, with two exceptions: Maine Sens. Olympia Snowe and Susan Collins who both scored 76 percent, or a "C." Republican Jim DeMint received the worst grade in the Senate, with a score of 10 percent.
By contrast, all Senate Democrats received a grade of "A," "B," or "Incomplete." A number of Democrats scored 100 percent.
Votes considered for the Senate scorecard included the confirmation of Hillary Clinton as Secretary of State, a vote in favor of the Lilly Ledbetter Fair Pay Act and a vote in favor of the American Recovery and Reinvestment Act, otherwise known as the stimulus act.
On the House side, all but a handful of Republicans received an "F." Rep. Ileana Ros-Lehtinen of Florida received the highest Republican score at 76 percent.
