This Party is often regarded as a failure because it focused on one issue (to increase the money supply) and tried to gain the support of farmers and workers, but the workers' wants and needs were different than those of the farmers, so the Populist Party didn't had all the support it needed to succeed and ended up being absorbed by the Progressive Party.
