This paper explores the contours of support for the state of Israel in the House of Representatives from 1997 to 2002. In an analysis of votes and cosponsorship decisions, we find that when Congress considers innocuous resolutions of support for Israel, support is consensual and nonpartisan. However, as the violence escalated between Israel and the Palestinians in the 106th and 107th Congresses (1999-2001), the House increasingly considered bills and resolutions that directly engaged the Palestinian issue and forced legislators to take a side in the ongoing conflict. This transformed the politics of support for Israel and increased the level of conflict among legislators. With that, new partisan, ideological, religious, and racial cleavages emerged. Democrats, liberals, and African Americans started to identify with the Palestinians—not Israel—as the oppressed group. At the same time, religious and ideological conservatives and Republicans started to identify with Israel as a just state under attack from lawless individuals considered to be outside the Judeo-Christian tradition. At least with regard to Israel, this suggests that the development of U.S. foreign policy, which is often characterized as an elite-driven pursuit of national interests, is heavily marked by domestic ethno-religious forces.
