Interestingly enough, it seems that Pappy did not in fact steal the 1941 election himself; he in fact had nothing to do with it. The alcohol interests stole it on his behalf; to "kick him upstairs", and out of their hair. LBJ tried to steal the election back, but his own people turned him down.

Fascinating books dealing with this story: Robert Caro--- The Path To Power,   and Charles R Townsend-- San Antonio Rose: The Life and Music of Bob Wills. I know of no book-length biography of Pappy O'Daniel ( but would sure read one if I could find it).
