The Republican members of the Caucus generally hail from solid Republican districts. But large swathes of the "red states" are not represented in the Caucus, including Montana, Utah and most of West Texas. More than half of the entire Caucus, that is 58 representatives, come from districts in the eleven states of the former Confederacy. Six of the eight Democrats in the HIRC are from the South.

While the geographic and demographic spread among Caucus members is relatively large, their voting records are tightly packed around staunchly conservative positions. For example, although these politicians have often couched their anti-immigrant positions in terms of concern about the earning power of native-born Americans, their voting record on labor issues averages a mere six percent. As measured by the American Federation of State, County and Municipal Employees, 86 members of the HIRC scored zero in support of labor.

Their records, as shown in the voting record appendix, are conservative on civil liberties, civil rights, and the environment. Further, the Caucus mirrors the Christian right on the two issues most associated with it: opposition to a woman's right to choose and gay rights. As measured by Planned Parenthood, 89 HIRC members with voting records in the 109th congress scored zero. The Human Rights Campaign, an advocacy group working for equal rights for gays and lesbians, measured all but four of the members at zero.

From this data emerges a picture of a highly ideological caucus, with its nativism one piece of a larger far right and ultra-nationalist whole. While not every HIRC member fits this mold, enough evidence exists to conclude that more than just the number of H1-B visas is at stake here.23
