The threat from within apparently defeated, Reid and his government turned their attention to the threat from without: the convention's repudiation had convinced Aberhart that his Social Credit League must run candidates in the next election. Reid's defence took two forms. The first was an overt attack on Aberhart and his policies. He insisted that Aberhart's proposed "monthly credit dividends" of C$25 could not be issued unless taxes increased tenfold. He argued that Aberhart's proposed means of raising revenue—"unearned increments" and "production levies"—were actually disguised taxes, which would be paid primarily by farmers, and that his claims that the necessary credit could be created "at the stroke of a fountain pen" on an accounting ledger were absurd. He further pointed out that elements of Aberhart's plan, including the provincial government's entry into banking and the creation of a provincial tariff, were "ultra vires" the province under the Canadian constitution. These themes were expounded on by Priestly and Brownlee, both of whom undertook speaking tours and radio addresses, and by legal and economic experts commissioned by the government.
