William Daniel

Daniel was elected to the state House of Representatives in the 1995 general election over Republican Sandra Bologna Ribes, 9,224 votes (52.9 percent) to 8,973 (47.1 percent). The seat was vacated by the Democrat Sean Reilly. Daniel and Ribes had led six other candidates in the nonpartisan blanket primary held a month earlier and hence entered the second round of balloting. In 1999, Daniel won a second term with 87 percent of the vote over an Independent candidate, Glenda Natale. In 2003, Daniel ran without opposition. In 2004, he ran unsuccessfully in the primary for the Baton Rouge Mayor-President consolidated position. He finished third with 27,662 votes (24.6 percent). Victory went to the African-American Democrat Kip Holden, whom Daniel endorsed in the general election. Holden is a candidate for lieutenant governor in the October 24, 2015 primary election.

After Daniel left the legislature, Mayor Holden named him to the six-month interim position as director of public works. However, Daniel stayed at public works for the full second term of Mayor Holden. In 2012, Holden elevated Daniel to his chief administrative officer.

In 2007, three Republicans but no Democrats entered the House District 68 race to choose a successor to Daniel. Lobbyist Kyle Ardoin, a Republican-turned-Democrat-returned-Republican, led the field with 5,531 votes (41 percent) to Steve Carter's 5,242 (38.9 percent). Jay Lyles received the remaining 2,705 votes (20 percent)s. In the second balloting on November 17, which had a lower turnout because of the lack of a gubernatorial contest, Carter prevailed by 87 votes, 4,967 (50.4 percent) to Ardoin's 4,880 (49.6 percent).

He has served on the boards of both Baton Rouge Community College and the Alcohol and Drug Abuse Council. In 1997, he graduated from the program "Leadership Louisiana" sponsored by the Council for a Better Louisiana. He is an Episcopalian. He and his ex-wife, the former Lynda Hiltz, have five children.
