The founders were wary of corporate influence on politics  and their rhetoric sometimes got pretty heated. In an 1816 letter, Thomas Jefferson declared his hope to “crush in its birth the aristocracy of our moneyed corporations, which dare already to challenge our government to a trial of strength and bid defiance to the laws of our country.”

This skepticism was enshrined in law in the early 20th century when the nation adopted strict rules banning corporations from contributing to political campaigns. Today that ban is in danger from the Supreme Court, which hears arguments next month in a little-noticed case that could open the floodgates to corporate money in politics.

The court has gone to extraordinary lengths to hear the case. And there are worrying signs that there may well be five votes to rule that the ban on corporate contributions violates the First Amendment.

The origins of the ban lie in the 1896 presidential race, which pitted the Republican William McKinley against William Jennings Bryan, the farm-belt populist. Bryan was a peerless orator, but McKinley had Mark Hanna  the premier political operative of his day  extracting so-called assessments from the nation’s biggest corporations and funneling them into a vast marketing campaign.
