I've exhausted every search string I can think of, but google is so completely useless. Unless I'm not remembering it correctly, it was a letter from a completely disenfranchised dust bowl farmer to the American president during the great depression stating "I vow to do everything in my power to bring about communism."

I swear I've read this multiple times, but can't find it on hexbear, reddit, or anywhere.

Would really appreciate if someone could help me find the source, original, or even a partial quote. Thank you.
