I suppose I'm never up on history, unless it is Music History. It was news to me. I did know about he and his wife being Spiritualists.    I can only imagine that the only reason it might matter would be the irony if "Father Abraham" founded the party which seeks to place restrictions on gays.
   I also dislike speaking of the deceased when they cannot speak for themselves, especially when the person is such an important person to our history. Whatever the case, he was exactly the person we needed at the time to bring the North & South back together as one United States of America. He was a great statesman.
   The book on my nightstand for many years, "Light From Many Lamps" has some of his writings and speeches. Read him sometime. He was a brilliant man.
