Incumbent Republican Jim Kolbe, who had represented the district since 1984, ran for re-election. He was re-elected with 63.3% of the vote in 2002.
Kolbe faced a serious primary challenge for the first time since winning the seat in 1984 from state representative Randy Graf. Graf ran well to Kolbe's right, with a message to "get tough" on illegal immigration, a "hot button" issue, especially for residents living along Arizona's border with Mexico, which has become a major crossing point for smuggling. He also aligned himself with U.S. Representatives Tom Tancredo of Colorado and Steve King of Iowa, who proposed enhanced border security. Graf was also a senior advisor for Proposition 200, an initiative passed by Arizona voters in 2004 to prevent welfare and voter fraud. He was also anti-abortion, against same-sex marriage, in favor of continued U.S. support for Israel, and in favor of tort reforms and medical care choice as a way of lowering health insurance rates.
