After fighting as an Israeli soldier in the 1973 war, and troubled by the nation's obsessive mixing of the Bible with politics, the filmmaker left for America, which he considered a "safe haven" because of its separation between church and state. Thirty-five years later, alarmed by the prominent role of religion in the 2008 American presidential campaign, he decides to make a road trip, to try and understand the phenomenon. Rather than follow the candidates, however, Ziv decides to meet with religious activists supporting the Democratic and Republican candidates. From the Iowa Caucus and the New Hampshire and South Carolina primaries to Super Tuesday in Oklahoma, JESUS POLITICS shows the efforts of Baptist activists for Obama, Catholics and evangelicals for McCain, Christian conservatives for Huckabee, as well as the political efforts of evangelical organizations such as Christians United for Israel.
