But during the day results from the Cape ate away at his margin until 2 p. m., when Keith, a strong Nixon supporter, passed him on his way to victory.

In the Tenth District, Bertram Yaffe, an antiwar Democrat, met an expected defeat at the hands of two-term Republican Congresswoman Margaret Heckler. After seesawing in the returns all night, Yaffe conceded at 8 a. m. yesterday, urging his supporters to continue working for peace candidates.

Drinan

In the Third District, the Rev Robert Drinan, dean of Boston College Law School, rode an antiwar platform to become the first Catholic priest ever to be elected to Congress.

In a race which received national attention, Drinan defeated two conservative opponents-Democratic incumbent Philip J. Philbin, whom Drinan had defeated in the Democratic primary, and Republican State Rep. John A. McGlennon.

Complete unofficial returns showed Drinan ahead with 64,716 votes, while McGlennon trailed with 61,129. Philbin, who ran a write-in campaign, brought up the rear with 45,734.

Drinan, who shares with a conservative Alabama Baptist minister the distinction of being the only clergymen elected to Congress, yesterday told his supporters he had won because "the people are looking for moraleadership." He predicted that "the loud and unsilent minority of war critics will grow to be an unsilent majority."

Harrington

In an expected victory, antiwar Democratic Rep. Michael Harrington routed his Republican opponent, Howard Phillips, by nearly 40,000 votes, thus winning his first full term in the Sixth District congressional seat he won in a special election last year.
