Businessman and 2002 Republican gubernatorial primary candidate Timothy James, State Representative Robert Bentley, Chancellor Bradley Byrne, and former state Supreme Court chief justice Roy Moore, were all major contenders for the Republican nomination. In the June 1 primary, Byrne finished in first place with 28.9%, followed by Robert J. Bentley who won 25.2% of the vote. Due to state law, the two were forced into a July runoff election, in which Bentley defeated Byrne by a margin of 56.1 to 43.9% to win the Republican nomination.
