Election Roundup

NEW YORK--U.S. Representative Edward I. Koch (D-N.Y.) won the New York City mayoral race last night. Koch, the Democratic Party nominee, had been the heavy favorite in the election.

Koch defeated Mario M. Cuomo, Secretary of State and the Liberal Party nominee, for the third time this year. Cuomo also lost in the Democratic primary and the runoff.

Republican candidate Roy Goodman and Conservative candidate Barry H. Farber trailed far behind Koch and Cuomo.

TRENTON. N.J.--Democratic Gov. H. Brendan Byrne was re-elected last night. Byrne defeated Republican candidate Raymond H. Bateman, a state senator.

Byrne, who instituted a state income tax last year, was so far behind in the polls six months ago that he considered not running again. President Carter campaigned for him this fall.

RICHMOND. Va.--Republican John Dalton last night defeated Democratic candidate Henry Howell in the Virginia gubernatorial race.
