Abolitionists Wanted to Kill Them

Southern writers proposed a counter theory, that it was a conspiracy of radical northern abolitionists who did it. It was claimed that franklin pierce's attorney general had received a letter from a pharmacist in philadelphia about an order of arsenic to kill buchanan. The papers allegedly documenting the plot were later allegedly seized by the government and so cannot be examined. This just doesn't make any sense. What about the idea that african americans did it? This one is really stupid. And what about those crafty, conniving jesuits? Another stupid theory.
