| | On September 30, 2006, Cain was defeated in a [[special election]] for state [[insurance]] commissioner by his fellow Republican [[Jim Donelon]] of Jefferson Parish in [[suburb]]an [[New Orleans]], who had succeeded to the position in 2006 on the resignation of J. Robert Wooley, a Democrat from Baton Rouge elected in 2003 but who had been acting commissioner from 2000 to 2003. Donelon won reelection in the nonpartisan blanket primary on October 12, 2019. In that race, Cain charged that Donelon, also a former Democrat, was insufficiently committed to Republican and [[conservative]] principles. However, Donelon pointed out that he had been a Republican for some twenty years longer than Cain and had carried the [[Republican Party (United States)|GOP]] standard in several important elections, including the [[U.S. Senate]] race in 1998 against the popular incumbent Democrat Senator John Breaux, when other Republicans were unwilling to commit to the challenge. | | On September 30, 2006, Cain was defeated in a [[special election]] for state [[insurance]] commissioner by his fellow Republican [[Jim Donelon]] of Jefferson Parish in [[suburb]]an [[New Orleans]], who had succeeded to the position in 2006 on the resignation of J.
