State Senate President Jason Boe and several other candidates for a chance to take back his Senate seat. Boe, who was 45, made Morse's age, 73, an issue in the race while Morse said his experience in the Senate made him a stronger candidate. Boe called for a series of debates around the state, but Morse refused. He went on to defeat Boe 49% to 39%, and planned to use the same strategy in the general election against Packwood, whose narrow victory over Morse 6 years earlier was attributed to Packwood's superior performance at a debate in Portland late in the campaign. In July, Morse was hospitalized in Portland with what was originally described as a serious urinary tract infection. His condition deteriorated and he died on July 22. The death was originally reported to have been caused by kidney failure, but it was later revealed that Morse died of leukemia; Boe apparently knew of the diagnosis during the campaign but did not make it a campaign issue. The Oregon Democratic State Central Committee met on August 11, two days after Richard Nixon resigned the Presidency. They chose State senator Betty Roberts over Boe to replace Morse as the Democratic nominee. Roberts, an Oregon State Senator, had run for the Democratic nomination for Governor that year, but lost in the May primary to eventual general election winner Robert W. Straub. Outgoing Oregon governor Tom McCall, who had decided not to run in 1968, had pledged to Packwood a year earlier that he would not challenge him in 1974. But as his term as governor ended, McCall began reconsidering his decision, believing he would bring more integrity to the job. In March 1974, at a dinner party held at Packwood's Washington D.C. home in McCall's honor, McCall informed Packwood that he would challenge him. The news of McCall's change of plans soon reached the media. Eventually, McCall decided that he had little chance against Packwood, who had similar positions to his own and had a reputation for ruthless campaigning that McCall did not share. McCall did not run, and Packwood was unopposed in the Republican primary. Strong Democratic gains were predicted, giving Roberts a good chance at an upset. In addition, the Senate had no female members and Roberts was one of three women (along with Barbara Mikulski in Maryland and Gwenyfred Bush in South Carolina) seeking a Senate seat. But
