I Smell A Rat...

I posted that Lincoln quote yesterday, but something seems a little fishy to me about it. Firstly, it just doesn't sound like the vernacular of the Civil War era. Secondly, after Lincoln's son Thaddeus died as a child, Mary Todd Lincoln went bat shat crazy in grief. She would hold seances trying to speak to her deceased son. That just makes me think Lincoln wouldn't say something like that.
