Large-scale electoral meltdowns are relatively rare. In Italy in 1994 the Christian Democrats went from having been the biggest party in every election since the late 1940s to virtual wipe-out. In Spain in 1982 the Union of the Democratic Centre, which had dominated the first parliament after the transition to democracy, fell from 168 seats to just 12, and effectively ceased to exist. The biggest single defeat for any party was probably that of the Progressive Conservatives in Canada in 1993, who fell from 151 seats to just two, though they later recovered. By all accounts, Fianna Fáil, the ruling party in Ireland, is facing electoral meltdown on Friday.
