Hoping to boost his popularity enough to avoid defeat, Hatfield delayed calling the election as long as possible. It was finally held on October 13, 1987, five years and a day since the last election—the longest allowed by the
Constitution of Canada. The Tories lost all of their seats, and Hatfield himself lost his own seat to Liberal challenger
Allison DeLong by 19 points. Taking full responsibility for the defeat, he announced his resignation the night of the election while being interviewed by media outside of his
Hartland home. Tory supporters had crowded into Hatfield's home, but abandoned him early in the evening as the returns began to come in.
Frank McKenna's Liberals were virtually assured victory from day one, thanks to Hatfield's scandals. However, they ran a very successful campaign that enabled them to garner an unprecedented clean sweep of the legislature. The
New Democrats also suffered a moral defeat, losing their one seat—something they had won for the first time in 1982. ==Opinion polls==
