When the provincial Liberals merged with John Bracken"s Progressives in 1932, Campbell led a group of dissident, anti-merger Liberals into the subsequent election. The group was known as the "Continuing Liberals", and ran candidates in 13 seats. Some within the new "Liberal-Progressive" alliance claimed that this new Liberal party was receiving financial support from the province"s Conservatives, as a means of dividing the Liberal vote.
Shortly before election day, the party claimed they would hold the balance of power in the next parliament.
The "Continuing Liberals" ceased to exist after the election, and the "Liberal-Progressives" remained in government until 1958.
