Foulds remains active with the New Democratic Party, and supported Bill Blaikie for the federal party's leadership in 2003. In 2005, he published an editorial in the Ontario party's newsletter, arguing that voters should reject the arguments of right-wing politicians, and recognize that tax dollars and government intervention may be beneficial for society. If governments continue to pursue right-wing policies, he argues, "we’re going to see more homelessness, more private health care, more private education, more gated communities, and more danger to your family and mine."
