(CNN) - Wisconsin's Democratic Gov. Jim Doyle announced Monday that he will not seek another term in the governor's mansion - and in the process, took an apparent swipe at former Alaska Gov. Sarah Palin.
"I have decided that I will not run for a third term as governor," Doyle told a gathering of supporters, but emphasized that he fully intends to serve out the remaining year and a half of his current term.
"Maybe I am old fashioned, but I believe strongly that when you run for a term, you serve the term. You work hard every day in that term and I am going to work as hard as humanly possible over this time to help the people of Wisconsin."
Doyle's comment was reminiscent of recent criticism of Palin who made a surprise announcement in June that she would step down from her office before her first term as Alaska governor was over. Palin transferred power to the state's lieutenant governor roughly three weeks ago amid rampant speculation about her possible aspirations in the next presidential election cycle.
Doyle told the audience that when he initially ran for governor in 2002, he and his wife assumed that, if elected, he would only serve two terms.
"As much as love this job, as hard as I work at it, as much as I think my team and I could contribute in a third term, I believe a governor should limit him or himself to two terms," said Doyle.
Doyle noted that two terms was the norm for most governors and for the president.
Doyle said he was announcing his decision now to allow anyone thinking about running for governor to step forward and get their campaigns going.
In the past few months, Doyle's approval rating has dropped into the mid-40s. In recent years, his approval ratings have been in the 50-60 percent range.
