It looks like Congresswoman Nancy Pelosi will get a bit of a challenge after all. Terry Baum,a member of the Green Party,now expects to join young Republican Jennifer DePalma,as a contender against Pelosi in November. Baum’s role in the race comes via a write-in campaign,the success of which she plans to announce Tuesday morning at City Hall. Baum,should the Elections Department indeed certify her victory,would be the first third-party write-in since a Black Panther slate did it in 1968,according to Baum’s campaign. Baum,a lesbian,recently challenged Pelosi to officiate a gay marriage,with no response from the congresswoman.
