David Gill, an independent candidate for U.S. House in the Illinois 13th district, has been challenged off the ballot. He needs 10,754 valid signatures and he was found to have only 8,593. According to this story, he will soon file a lawsuit challenging the number of signatures needed by independents for U.S. House in Illinois.
In all of Illinois history, no petitioning candidate for U.S. House in the general election has ever overcome a petition requirement greater than 9,698, if the petition was challenged. The toughest petition requirement ever met by an Illinois petitioning candidate who was challenged was the 9,698 required in 1974 in the 15th district. That candidate was K. Douglas Lassiter.
