Analysis of "A Letter to Horace Greeley."

Within the vast scope of non-fiction, I seem to skip over the plot of land that covers political writing.  Political speaking.  It sounds yawny to me.  

Colbert is the exception to
political tediousness.

And yes, I just invented that adjective. It's like brawny, but...yawny.  Lame.  Tiring.  Tedious.  Boring.  

So, as part of my self-directed learning plan, I want to study a little more political writing.  Within an anthology of letters, I found this little gem:

A letter to Horace Greeley, from Abraham Lincoln, in response to an article written by Greeley, titled "The Prayer of Twenty Millions." I decided to take a stab at it critically (inspired by Dr. Burton's review of Neal A. Maxwell's dissection of two sermons) ; being careful to analyze the appeals to ethos, logos and pathos, while also examining kairos: the timeliness of the exchange.
