Who Said This?

Who said this, or who wrote this?
The following takes place before the Republican Convention of 1864

Within a month of his nomination, and when his more violent enemies had abandoned the effort to defeat him, as was evidenced by the Fremont Convention called at Cleveland, he was yet perplexed with anxiety over the possibility of his defeat. In discussing the question as late as May, 1864, I was surprised to find the apprehensions he cherished. I told him that his nomination was a foregone conclusion, and that it was not possible for any combination to be made that could endanger his success. I presented the attitude of the various states, and referred to their delegations to prove to him that his nomination must be made on the first ballot by a two thirds vote, if not with absolute unity.

To this he responded: "Well, XXXXXXXe, what you say seems to be unanswerable, but I don't quite forget that I was nominated for President in a convention that was two-thirds for the other fellow."
