Year by year, each Congress grows more diverse, but the list of the most liberal and conservative members is also interesting when examined by race.

National Journal looked at votes on key issues during the 112th Congress to determine members' rankings. The Top 25 most-conservative House members were all Republicans; the list includes two people of color:

18th (tie): Bill Flores,  Texas
23rd: Francisco "Quico" Canseco, Texas

The list of the Top 25 most-liberal House members includes the names of 26 Democratic lawmakers because there were several ties. Based on NJ's methodology, 14 individuals tied for being the most liberal; 10 of them are people of color. The entire Top 25 list includes 16 people of color.
