The 1988 United States Senate election in Florida was held on November 8, 1988. Incumbent Democratic U.S. Senator Lawton Chiles decided to retire instead of seeking a fourth term. Republican Connie Mack III won the open seat, becoming the first Republican to hold this seat since Reconstruction.[1]
This senate election was heavily targeted by both parties. U.S. Representative Mack announced his candidacy back in October 1987.[5] President Ronald Reagan endorsed Mack in June 1988[6] to allow Mack to focus on the general election, as he easily won the September 6 Republican primary against U.S. Attorney Robert Merkle.[7] In May 1988, MacKay announced he would run for the open seat,[8] and defeated Insurance Commissioner Bill Gunter in a close October 4 runoff primary election.[9]
The general election became very nasty. MacKay tried to portray the Republican as "extremist."[10] Mack attacked his opponent in television ads by connecting him to unpopular Massachusetts Governor and presidential candidate Michael Dukakis.[11] Mack had help from vice presidential candidate Dan Quayle.[12] The election was so close there was a recount until MacKay conceded eight days after election day.[13]
