“In the following list, House members are assigned separate scores for their roll-call votes on key economic, social and foreign-policy issues during 2009. The members are rated in each of the three issue categories on both liberal and conservative scales, with the scores on each scale given as percentiles. An economic score of 78 on the liberal scale, for example, means that the member was more liberal than 78 percent of his or her House colleagues on the key votes in the issue area during 2009.”
