Dan Coats
When Quayle resigned from the Senate after being elected Vice President of the United States in 1988, Coats was appointed to Quayle’s former seat. Coats was subsequently elected to the seat in 1990 and 1992 and served in the Senate until January 1999, when Evan Bayh became the new Senator. Coats announced on February 3, 2010, he would run for his old Senate seat and on February 16, 2010, Bayh announced his intention to retire. Coats went on to win that Senate seat.
