On May 23, 2012, the Columbus (Ohio) Metropolitan Club used corporate donations to host a forum on “Presidential Politics in Ohio”. The only two speakers were the chairs of the Ohio Republican Party and the Ohio Democratic Party. On June 4, Ohio law professor Mark Brown asked the Federal Election Commission to determine that the two major parties illegally received corporate contributions, because the event organizers did not invite the state party chairs of any of Ohio’s other ballot-qualified parties to participate.
The federal law that provides for the Federal Election Commission permits any voter to have standing to file such a complaint. Here is the Complaint.
