None of the secession documents (what we're always told to read) call Lincoln a Bumpkin. The primary objection to Lincoln was that he represented only one part of the country and was elected purely along sectional lines. Even so...
Country Bumpkin Lincoln and the Blockade...
James Lorimer, Studies National and International, 42-43:
...the blockade, it seems, was a mistake; I do not mean a mistake of policy, but a mistake of ignorance and want of thought. "When the war broke out," says Mr. Thaddeus Stevens, the venerable President of the Chamber of Representatives, "my opinion was that it ought to be treated as a simple rebellion, and that all those who took part in it ought to be considered as traitors against the Government of the United States. It was thus that Congress understood it; and I supposed that Mr. Lincoln and his Cabinet understood it in the same way. After the termination of the first session of Congress which took place under Mr. Lincoln's presidency, and very shortly after my return home, I read, to my great surprise, a proclamation, declaring the blockade of the rebel ports. It was a gross mistake, and an absurdity. If the rebel states were still part of the Union, and only in revolt against the Government, we were establishing a blockade against ourselves; we were blockading the ports of the United States. I immediately attributed the affair to the incomprehensible policy of Mr. Seward, and set off for Washington to see the President, Lincoln, and speak to him on the subject. I explained to him my view of the matter. I said to him that the blockade annihilated the position originally taken up by the Government with reference to the rebel States; that the ports, in place of being blockaded, ought to have been shut; and that all that was requisite was to have armed a sufficient number of the vessels of the coastguard to prevent contraband. I explained to him that by the mere fact of the blockade we recognised in the rebel States the character of independent belligerents, and that we should henceforth be forced to conduct the war not as if we were extinguishing a revolt, but with all the formalities of international law.
"' You are quite right,' Mr. Lincoln said, after hearing me out, 'I see the distinction now. But I knew nothing about international law, and I thought we were quite en regle [in order].'
"' As an advocate, Mr. Lincoln,' I said to him, 'I should have expected the difficulty at once to present itself to your mind.'
"' The reason, don't you see,' replied Mr. Lincoln, 'is this. I was a pretty fair advocate in one of our Western Courts; but we have very little international law down there. I thought Seward had been up to all that sort of thing, so I let him have his way. It's done now, and we can't help it. We must make the best we can of it.'
"In that Mr. Lincoln was right. The mistake was made, and the rebel States from that time were an independent belligerent, —I don't say, mind you, an independent nation,—but certainly an independent belligerent, whom it was necessary to treat according to the rules of international law."
