Through the 1940s and 1950s, the CCF's vote percentage declined, eventually falling under 10 percent. At any one time, the party never won more than two seats. The party was kept to two MLAs throughout the 1950s. Roper lost his seat in the 1955 election. In the same election, Stanley Ruzycki and Nick Dushenski were elected. Roper was succeeded as party leader by Floyd Albin Johnson. The 1959 general election was a disaster for the CCF, losing both its existing seats while Johnson, running in the Dunvegan electoral district, failed to win his seat, leaving the party shut out of the legislature.
