Campaign

This senate election was heavily targeted by both parties. U.S. Representative Mack announced his candidacy back in October 1987. President Ronald Reagan endorsed Mack in June 1988 to allow Mack to focus on the general election, as he easily won the September 6 Republican primary against U.S. Attorney Robert Merkle. In May 1988, MacKay announced he would run for the open seat, and defeated Insurance Commissioner Bill Gunter in a close October 4 runoff primary election. The general election became very nasty. MacKay tried to portray the Republican as "extremist." Mack attacked his opponent in television ads by connecting him to unpopular Massachusetts Governor and presidential candidate Michael Dukakis. Mack had help from vice presidential candidate Dan Quayle. He also ran ten-second television advertisements that said "Hey Buddy, you're a liberal," a charge MacKay could never escape. The election was so close there was a recount until MacKay conceded eight days after election day.
