What were the effects of the populist party on american politics and economics? did they have an effective party platform, or at least did their platform put pressure on the other parties of the era to change?

They didn't have a truly effective party platform as they were not organized as a party but rather as a group of people who want changes. They didn't really think much of things like presidencies as long as their needs were fulfilled. This led to their downfall because their policies were adopted by the Democratic Party which took away their supporters, and the group disbanded soon after. Their policies were introduced but they disbanded so it was a victory of sort in the end.
