DINKINS BEATS KOCH IN NEW YORK MAYORAL PRIMARY

David Dinkins (D), Manhattan borough president, will face former federal prosecutor Rudolph Giuliani (R), after the two won their respective primary elections Tuesday. Meanwhile in Detroit, accountant Tom Barrow beat US Rep. John Conyers (D) in the city's nonpartisan mayoral primary to win a spot in a runoff against four-term incumbent Coleman Young.

In other elections Tuesday, Democrats foiled Republican designs on House seats in Texas and California that were vacated by Speaker Jim Wright and Democratic Whip Tony Coelho.

Mr. Dinkins received 51 percent of the vote, while incumbent Edward Koch garnered 42 percent. Dinkins is the first black to win a major party nomination in New York. Mr. Giuliani defeated cosmetics heir Ronald Lauder in the Republican primary with 67 percent of the vote.
