According to this story, Montgomery County, Maryland, officials are trying to disqualify a referendum petition from the ballot because two of the circulators are ex-felons. However, any adult in Maryland is legally qualified to circulate a petition.
The story has more human interest than it would otherwise, because the sponsor of the referendum is the union that represents police officers. Also one of the two circulators is a fugitive. Thanks to Eric Garris for the link.
