From the Baltimore Sun:
Democratic presidential candidate Martin O’Malley failed to submit enough valid signatures to appear on Ohio’s primary ballot in March, a state official said Thursday.
O’Malley, the former Maryland governor who is running a longshot campaign for the nomination, submitted 1,175 signatures to the Ohio Secretary of State, 175 more than required for ballot access. But state officials have determined that only 772 of the signatures are valid, said Gia Harrison, a deputy press secretary in the office.
Signature requirements are how political parties cull the (in their minds undeserved candidates from the voting poll. Third Party candidates KNOW they have to get ten times the number of signatures that are required by law, because party hacks are absolutely shameless in their ability and willingness to challenge. And the number of signatures are often ten times the number required by law anyway.
I’m guessing that Bernie is considered mainstream enough, so he’s nat facing a challenge to his signatures.
