Lincoln and Hamlin?

[L Verge]

I have no good background in Lincoln studies, but I have always considered him a master politician (and manipulator). Personally, I cannot see him sitting back and letting someone else choose the VP that he would have to work with to complete the war and begin Reconstruction.

It appears from what I have read that Hamlin had been pretty much of a waste in the job. Despite Burlingame's assessment, would Lincoln really want four more years of working with (or ignoring) him? And yes, I know that Johnson started out shaky with Lincoln also. Didn't Johnson have his military governorship of Tennessee working for him, however?
