I found out recently that Guthrie rented from Trump's dad, Fred and loathed him so much he wrote a song, 'Old Man Trump'. It wasn't recorded, but I came across this on YouTube which purports to be the only recording of Guthrie mentioning Trump.
"I suppose Old Man Trump knows Just how much Racial Hate he stirred up In the bloodpot of human hearts When he drawed That color line Here at his Eighteen hundred family project."
The discovery was covered by the MSM, so I guess I just missed it.
