Marijuana Legalization Initiative Kept Off Ohio Ballot

The same thing happened to Ralph Nader in 2008: a shockingly high number of petitions were deemed invalid for a variety of reasons. I wonder if there's a higher than average signature rejection rate in Ohio:

COLUMBUS — An effort to legalize medical marijuana in Ohio was stopped in its tracks Wednesday when supporters failed to get enough valid signatures on petitions, according to Ohio Attorney General Mike DeWine’s office.

The proposal needed 1,000 signatures, but just 534 of the 2,134 turned in by supporters were deemed to be valid, according to a release to the media from DeWine’s office. That's about a 75% rejection rate for signatures. I've seen quite a few blog posts and tweets laughing about this as though the petitioners were just stoned slacktivists who didn't step up to the challenge. But getting over 200% of required signatures seems pretty on-the-ball to me. Something about this feels off.
