Which of the populist parties Policies undermined its attempts to appeal urban workers

Answer: Congress's policies undermined its attempts to appeal to urban workers.

Explanation: The Populist effort was probably doomed from the start. They advanced a number of stellar ideas but fell prey to the allure of free silver, an issue that resonated poorly with urban workers whose votes were badly needed. Discontented farmers, despite their enthusiasm, simply lacked the numbers to move the nation.
