Ohio’s current Treasurer Josh Mandel (R) is challenging Sen. Sherrod Brown (D) for his seat in 2012. Running on the “tested and trusted” tagline, Mandel is failing the basic test of transparency. On April 6, Mandel filed paperwork for his Senate campaign with the Federal Elections Commission. According to federal law, a candidate’s personal financial disclosure must be filed within 30 days of declaring or after raising $5,000. But 90 days later, after both declaring his candidacy and raising $2.3 million for his race, Mandel has still failed to disclose. Indeed, the Secretary of the Senate’s office confirmed to ThinkProgress that no forms have been filed. By law, he is subject to a $200 fine. Mandel also faces a FEC investigation for violating another federal election law by using resources from the Treasurer’s office to support his candidacy.
