I am analysing the history of demagogy and it's rhetoric using modern data science. I have acquired some collections of speeches dating back to George Washington, but unfortunately I have not been able to find anything beyond "Enemies from Within" from McCarthy.
I know that there are transcripts from Senate hearings in which he appeared, but he doesn't say very much in those so they are of no big help.
He was known for his extreme anti-communist public speeches, so it seems odd that there are not transcripts of those. Maybe this community can help me out?
