The last provincial election had been held in June 1917, and four years was the normal life of a legislature in Canada. Stewart called an election for July 19. Though the Liberals' fortunes had been sagging in the post-war years, there remained no doubt that they could again defeat the Conservatives; their real challenge was evidently from the newly politicized UFA. Bolstering this challenge by increasing farmers' discontent was a collapse of agricultural prices. The UFA had no leader, no fixed platform, and no inclination to attack Stewart or his government. What it did have was superior organization, and on election day this organization made itself felt in the form of thirty-nine UFA members elected to fourteen Liberals. Stewart, who has been acclaimed in his own riding of Sedgewick, announced that he would resign as Premier as soon as the UFA had selected somebody to replace him. Once it selected Herbert Greenfield, Stewart made good on his pledge, and Greenfield replaced him August 13.
