Lawmakers stuffing a bill with goodies for their home district are said to be raiding the pork barrel. The story behind the phrase is murkier, and darker, than most people think.
Pork barrel means government spending aimed at a lawmaker's own district, often tucked into a larger bill, designed to please local voters and win their support. A bridge, a research center, a harbor project: pork.
The popular origin story is grim. It is often said the term comes from the pre-Civil War South, where enslaved people were given salt pork from large barrels and would rush the barrel to grab a share, and that members of Congress scrambling for funds were likened to that scene. A 1919 article by Chester Collins Maxey drew exactly that comparison.
But careful etymologists are skeptical. Researchers who have traced the phrase find no solid evidence linking it to slavery, and note that the political sense did not lock in until decades after the Civil War, around the turn of the twentieth century. The salt-pork story may be folklore attached to the phrase after the fact.
What is clear is the practice. Before refrigeration, pork really was stored in barrels of brine, and by the 1870s pork was common slang in Congress for local spending grabbed from the public treasury.
