He narrowly won the general election of 1991 and prevailed comfortably in the nonpartisan blanket primary in 1995 as a Democratic Party (United States)/Democrat.

Greene did not seek a third term in the Senate in the 1999 primary. Instead, he challenged fellow Democrat-turned-Republican Governor of Louisiana/Governor Murphy J. Foster, Jr./Murphy J. "Mike" Foster, Jr. in the gubernatorial primary, but polled only 35,434 votes (2.7 percent).More Tom Greene on Wikipedia.
