Lincoln and Hamlin?

[RJNorton]

Looks good to me, Bill.

I believe, over the years, I have read (in various sources) three different scenarios on how Johnson was selected for VP at the convention:

A. Johnson was picked without any contact with Lincoln.
B. Johnson was selected, and then Lincoln gave his personal approval.
C. Hamlin was dropped, and Johnson was selected per Lincoln's instruction.

Any thoughts?
