Lincoln was a Marxist

A Groucho-Marxist, at any rate: Groucho is reputed to have said, "I refuse to join any club that would have me as a member."

As a young man, considering his matrimonial prospects, Abraham Lincoln wrote:

I have now come to the conclusion never again to think of marrying, and for this reason; I can never be satisfied with any one who would be block-head enough to have me.

That's from a letter Lincoln wrote after his proposal of marriage was rejected by a woman to whom he wasn't attracted. (He proposed out of a sense of obligation from a frivolous promise he made to the friend of his potential fiancee.) His description of his first impressions of the woman in question is vivid:

In a few days we had an interview, and although I had seen her before, she did not look as my immagination had pictured her. I knew she was over-size, but she now appeared a fair match for Falstaff; I knew she was called an "old maid," and I felt no doubt of the truth of at least half of the appelation; but now, when I beheld her, I could not for my life avoid thinking of my mother; and this, not from withered features, for her skin was too full of fat to permit of its contracting in to wrinkles; but from her want of teeth, weather-beaten appearance in general, and from a kind of notion that ran in my head, that nothing could have commenced at the size of infancy, and reached her present bulk in less than thirty-five or forty years; and, in short, I was not all pleased with her.
