Lewis's politics were heavily influenced by the Jewish Labour Bund, which contributed to his support of parliamentary democracy. He was an avowed anti-communist, and while a Rhodes Scholar prevented communist domination of the Oxford University Labour Club. In Canada, he played a major role in removing communist influence from the labour movement.

In the CCF, he took the role of disciplinarian and dealt with internal organizational problems. He helped draft the Winnipeg Declaration, which moderated the CCF's economic policies to include acceptance of capitalism, albeit subject to stringent government regulation. As the United Steelworkers of America (USW)'s legal counsel in Canada, he helped them take over the International Union of Mine, Mill, and Smelter Workers (Mine-Mill). His involvement with the USW also led to a central role in the creation of the Canadian Labour Congress in 1956.

The Lewis family has been active in socialist politics since the turn of the twentieth century, starting with David Lewis's father's involvement in the Bund in Russia, continuing with David, and followed by his eldest son, Stephen Lewis, who led the Ontario NDP from 1970 until 1978. When David was elected the NDP's national leader in 1971, he and Stephen became one of the first father-and-son-teams to simultaneously head Canadian political parties.
