Maryland law stipulates that a new political party must show that its membership comprises at least 1 percent of registered voters or that the party's nominees for governor of Maryland received at least 1 percent of the total vote in the latest election. Because Maryland Greens have never commanded 1 percent of the votes in any gubernatorial election, it must turn into the State Board of Elections 10,000 verifiable signatures of registered Greens to remain on state ballots. In March 2010, the Green Party's ballot petition was rejected when the Board of Elections ruled that only 5,919 signatures of nearly 15,000 collected were valid. What might make a signature invalid? If you included your middle initial when you registered to vote, but forgot to subsequently write it on a ballot access petition, for example, your signature is nixed. A lawsuit filed in conjunction with the Maryland Libertarian Party was appealed all the way up to the Maryland State Court of Appeals, which ultimately ruled in May 2012 that signatures on ballot petitions are invalid if there are no exact matches in the state voter registration record, forcing the Green Party to collect over 4,000 more signatures in the span of a few months to remain on the 2012 ballot.
