You wrote of Sen. George W. Della of the 46th District: "By and large, he votes the way people in his district would want, he is independent of the leadership in Annapolis, he is accessible to his constituents and he has experience in the ways of the Senate." ("For Bill Ferguson," Sept. 9) You then add that it would take Senator Della's opponent "a long time to match" his proven record but that the young man has "potential." Query: Would The Sun drop H.L. Mencken for an upstart just out of journalism school? I don't think so! Vote Della in the 46th District!
