## General election
### Campaign

During the campaign, Hendriksen primarily attacked Hatfield by stressing what she perceived to be flawed priorities. Hatfield was often criticized for the scandal involving Basil Tsakos, but the controversy of the scandal declined over the course of the campaign. He was also criticized by those who stressed environmental protection for his support of President Reagan's appointment of James G. Watt to the position of Secretary of the Interior. However, Hatfield's in-person campaign strategy proved successful, as he beat Hendricksen by 402,040 votes, and gained nearly double her percentage.
