An Open Question

A few days ago, Katie Naranjo and Jamarr Brown launched their campaign website for President and Vice President, respectively, of College Democrats of America. The CDA Constitution requires that the President and Vice President be of opposite sexes?. My question is: what happens if one of the two is transgendered/transsexual? The Democratic Party is supposed to support people of any sexuality, but how do we as a party determine a person's sex?
