Abraham Lincoln Suicide Poem?

[RJNorton]

Three arguments given by Joshua Shenk that Lincoln probably wrote this are (from p. 41 of Lincoln's Melancholy): (1) it has the same meter as Lincoln’s other published verse; (2) it is close to the date given by Speed when he told Herndon about it; (3) its syntax, tone, reasoning, and references are characteristic of Lincoln.

Personally, I am going to straddle the middle on this. I have no strong feeling either way whether Lincoln wrote it. He was prone to periods of depression, so it's possible he did write it I suppose.
