Traits of Office Seekers
Most elected officials are older, white males and usually wealthier than the average citizen. In the last few decades, more women and minorities have taken office at the state and federal levels, but they hold office in disproportionately low numbers. Following the 2002 elections, for example, just sixty-two women served as members of the House. After the 2004 elections, only one African American served in the Senate. The homogeneity of officeholders does not reflect the diversity of the population of the United States.
