As the elections scheduled for 1990 approached, Hoyte, under increasing pressure from inside and outside Guyana, gradually opened the political system. After a visit to Guyana by former U.S. President Jimmy Carter in 1990, Hoyte made changes in the electoral rules, appointed a new chairman of the Elections Commission, and endorsed putting together new voters' lists, thus delaying the election. The elections, which finally took place in 1992, were witnessed by 100 international observers, including a group headed by Carter and another from the Commonwealth of Nations. Both groups issued reports saying that the elections had been free and fair, despite violent attacks on the Elections Commission building on election day and other irregularities.
