The state of Maryland has enacted a statute governing the issuance of absentee ballots in state elections. Under the statute, any male under the age of 65 will be issued an absentee ballot only upon written proof that the applicant will be unable to be present at the voting place on the scheduled day for the election. If the applicant is female, however no written proof is required, and the applicant's statement that she cannot be present at the polling place is accepted at face value. The motivation for the statute was the legislature's belief that many women voters are the mothers of infants, who cannot easily get to the polling place to vote. Marvin, a male resident of Booth, has attacked the requirement of written proof on the grounds that it violates his Fourteenth Amendment equal protection rights. Will Marvin succeed in claim to invalidate the statute?
