I know Mormon leader Joseph Smith was in Illinois at this time. Is he the person referred to in the article?

[RJNorton]

Excellent, Anita! Indeed it was Joseph Smith, the Mormon leader. As far as I know, there is no evidence Smith and Abraham Lincoln ever met.

Stephen Douglas defended Smith in a court case. Smith later predicted that Douglas would run for President but lose if he ever hurt the Latter Day Saints. (Wikipedia)

Before he became President, who was Lincoln referring to when he wrote "_____________ has just concluded the very best speech, of an hour's length, I have ever heard"

I wrote your next clue would come tomorrow, but now it's already today, and here is your next clue.

Lincoln heard this speech in 1848 and wrote to William Herndon about it.
