Ohio Secretary of State Jon Husted certified the 2016 primary ballots on Thursday, identifying all of the candidates who will appear. On the Democratic ballot, voters will choose between Hillary Clinton, Bernie Sanders and Roque De La Fuente, a San Diego-based businessman.

O’Malley, who is polling third behind Clinton and Sanders nationally, fell short of the 1,000 required signatures to appear on the ballot. While the campaign submitted 1,175 signatures, only 772 were deemed valid according to the Secretary of State’s Office.

O’Malley’s campaign press secretary said in a statement, “while this news is disappointing, we are exploring all of our options, and Governor O’Malley will campaign vigorously in Ohio.” O’Malley, the press secretary added, is already on the ballot in 18 other states.
