On the last day for filing Illinois petition challenges, Rob Sherman filed challenges to the statewide petitions of the Constitution Party and the Socialist Party. He also challenged the petition of independent presidential candidate Mary Vann. These challenges mean that these parties and candidates will not appear on the ballot, because the petitions have substantially fewer signatures than the legal requirement of 25,000.
Rob Sherman is a Green Party member, and is a Green Party nominee for U.S. House this year. However, the Illinois Green Party does not support his actions. Sherman filed similar objections to the Constitution Party and the Socialist Party in Illinois in 2012.
No one has challenged the Libertarian or Green Party petitions, although the period for filing challenges still has not closed. The deadline is July 5 at 5 p.m. Illinois time.
