@turquoise-- I'm guessing so.
There was no way that Greenbacks would last after the Resumption Act was passed. They only lasted as long as they did because labor organizations joined them. And Greenback Party did take the correct stand by adjusting their agenda to gather more supporters. Suffrage and graduated income tax was far from their original platform.
But everyone knew that the Greenback Party had little to offer for the long term. Even if they did, the other parties were far too popular to compete with. I think it's an accomplishment that they even lasted ten years.
