HOW THIS WORKS
Letter grades were awarded
according to the chart below.

A letter grade of 'A' was awarded for a score of 90 and above. A letter grade of 'B' was awarded for a grade of 80 and above; a 'C' was awarded for a score above 50; a 'D' for a score above 40; and an 'F' for all scores below 40.

Scores for the general body of both the House and the Senate on a particular piece of legislation were determined by an average of the number of votes cast with or against the middle class.

Scores for the general body of the House and Senate themselves were determined as an average of the
scores each received on legislation held to a vote. Scores for individual representatives were determined by whether they voted with or against the middle class. Representatives who missed three or more votes were not awarded a letter grade and instead received a grade of Incomplete (INC). Aindicates that a representative voted WITH the middle-class position (not necessarily for the legislation); an indicates that the representative voted AGAINST the middle-class postion. A indicates that no vote was cast.
