She was nominated to the office by Governor Jeb Bush in February 2003 to replace Frank Brogan, who resigned to become president of Florida Atlantic University. She was sworn in on March 3, 2003, becoming the first woman to hold the office. She declined to run for governor in 2006 even though she was reputed to be Bush"s preferred choice as his successor.
After the 2006 elections, Jennings was replaced as Lieutenant Governor by Jeff Kottkamp on January 2, 2007.
Jennings previously served in the Florida House of Representatives from 1976–1980, and in the Florida Senate from 1980-2000. In 1994, when Orange County Chairman Linda Chapin announced she was not seeking re-election, she failed to convince Jennings to return to Orlando and campaign for the office herself.
Instead, she remained in Tallahassee to be elected by her Senate peers to be President of the Florida Senate—the only person to have held the powerful office for two terms, from 1996-2000. In 2000, legislative term limits came into effect, having been instituted by a constitutional referendum taken several years earlier.
Jennings was thereafter prohibited from seeking reelection.
