The D.C. Board of Elections and Ethics said yesterday that 60,000 new voters have registered this year and that the city's longstanding problems with inaccurate registration rolls have been solved.

The board has produced a master list of 274,810 registered voters -- 59 percent of those eligible -- which is expected to grow by 10,000 by the Nov. 6 election.

The board began a major effort in 1983 to rebuild its voter rolls by revalidating all voters. As a result, the board has taken registration rolls that once listed more than 400,000 voters and created a master list of 274,810 verified registrants.

The master list is made up of 222,539 Democrats, 21,747 Republicans and 1,327 Statehood party members.

Elections officials expect a record number of 200,000 voters for the general election and say that the system will be put to its greatest test. While results for all the candidates listed on the ballots will be known on election night, write-in votes will take much longer to count.

In the case of incumbent City Council member Jerry A. Moore Jr.(R-At Large), who is conducting an organized write-in campaign, it will take the board up to 10 days to learn how many votes Moore got.

On election night, a computer count will indicate how many voters punched the ballot for the write-in position and whether the number of write-in votes could make a difference in the outcome of the at-large race. But a hand count will be necessary to determine who received the votes and to count the write-in votes for which voters did not also punch the cards.
