Gardner first entered Ohio politics in 1985, when he was appointed to a seat vacated by former State Representative, Robert Brown. He went on to serve 7 more full terms in the House, until the time being term limited in 2000. With State Senator
Bob Latta not running for reelection to his seat, Gardner decided to run in 2000. He did, and in 2001, took his seat in the upper chamber. He quickly rose in the ranks, and served as president
pro-tempore for the
125th General Assembly. In 2004, he faced weak opposition, and once again won his senate bid. He served as majority leader for the
126th General Assembly and the
127th General Assembly. With
then-Senate President Doug White facing term limits, Gardner and Senator
Jeff Jacobson were looked at as two potential successors. However, by the end of 2003, Gardner had withdrawn as a candidate, citing the desire to eliminate uncertainty in the
caucus. Soon after, Jacobson in early 2004, became associated with a lobbying scandal, and Gardner once again emerged as a potential contender. In late summer 2004, he once again withdrew, and gave his support to
Bill Harris, who went on to become president. Gardner made it evident half way through 2007 that he intended to run for his old House seat in 2008, when he faced term limits in the Senate. However, when Congressman
Paul Gillmor was found dead in his
Washington D.C. area apartment, Gardner was mentioned as a potential successor, but on September 17, 2007, Gardner stated he was staying in the state legislature. When
Bob Latta ended up winning the congressional race to succeed Gillmor, Latta's 6th District Ohio House seat became vacant. Gardner therefore resigned his Senate seat and was appointed early to the seat he was running for in the fall. He was subsequently placed as ranking member of the Higher Education Subcommittee of the Finance Committee. ==Return to the Ohio Senate==
