The Socialist/Communist movement got it's impetus and have been pushing the DUmmies since at least the 1880s and William Jennings Bryan. They never got a great foothold here until WW I but they've been around. There was a LOT of Socialist support for Woodrow Wilson and even Theodore Roosevelt (because of trust busting).
William Jennings Bryan gave the "Cross of Gold" speech, yet it was Nixon who took America off the gold standard.
