at a campaign event. Campbell, who was unable to seek another term in the Senate in 2006 due to term limits, announced in 2005 that he would run for
Attorney General of Florida. He cited his experience as a private practice attorney and pledged to prosecute gas companies for price-gouging in the aftermath of
Hurricane Katrina. He was opposed in the Democratic primary by Merrilee Ehrlich, a trial attorney, who announced her campaign on the premise of providing Democratic primary voters "an option and a viable one." Campbell suggested that Ehrlich joined the race "in a misguided, but benevolent, attempt to give him statewide exposure by forcing the primary," though he denied that he was behind the effort. Campbell was endorsed by the
Sarasota Herald-Tribune and
The Ledger in the Democratic primary; the
Herald-Tribune praised his "skills and experience" to handle the job, while the
Ledger called him "a worthy contender" for his experience in the legislature. Campbell ended up defeating Ehrlich handily, winning 65% of the vote to her 35%. In the general election, Campbell faced former United States Congressman
Bill McCollum, the Republican nominee. During the election, Campbell campaigned as a moderate Democrat, citing his experience in the Republican-dominated State Senate as an example. Campbell was endorsed by the
Sarasota Herald-Tribune once again, which argued that he was "more familiar with state issues than McCollum," and that his "philosophy is representative of mainstream Florida." He was also endorsed by the
Tallahassee Democrat, which noted that, although the two candidates were alike, Campbell "deserves to be the state's top law-enforcement official because of his proven ability to foster bipartisanship and his record in private life as a top-flight attorney." Ultimately, however, McCollum narrowly edged out Campbell, winning with 53% of the vote to Campbell's 47%. ==State Senate campaign==
