Thirteen incumbents, including two former officers, were upset in last week's Undergraduate Council elections. But most of the contenders for top council positions received strong mandates from their electorates.

Outgoing Chair David A. Aronberg '93 of Currier House and chair candidates David L. Duncan '93 of Winthrop House and Malcolm A. Heinicke '93 of Eliot House easily won the most votes in their respective houses.

J.D. LaRock '95, who had been pursuing an aggressive campaign for chair, failed to win a seat at Quincy House. Last spring's Secretary Peter K. Lee '94 of Kirkland House was also unseated.

Mark D. McKay '94 of Kirkland House, who has announced a bid for chair despite quitting the council last winter, captured his house's fourth seat.

Michael P. Beys '94, the outgoing treasurer and chief organizer of the spring De La Soul concert which lost over $10,000, secured a comfortable second-place finish in Mather House behind roommate Sean M. Becker '94.

Beys, who has not yet announced his intentions, is expected to run for vice chair.

After a week of door-to-door campaigning, hand shaking, and finger pointing by prospective members, 57 newcomers will joining the 88-member council. Twenty-one of the new delegates are first-years.

Results of last week's elections were released on Saturday night.

Incumbent Vladimir V. Ragulin '94 ended on the losing side of a pitched battle at Adams House.

Ragulin and fellow Adams House incumbent Gian G. Neffinger '93 traded blows throughout the week in a campaign that many house residents described as "nasty". The negative campaigning culminated with a Neffinger poster declaring, "Hey Vlad--Suck Me."

Quincy House was the site of a furious 10-way race for six seats.

Though LaRock, a chief critic of last year's council, lost, winning was not too difficult for other incumbents.

Steven N. Kalkanis '93, a chair candidate last fall, received the most votes in Quincy House for the third year in a row, despite the wide field of candidates competing there.

"One of the things that has helped me out, is that I have always kept in close contact with the house," said Kalkanis. "People remember that."

Gil B. Lahav '94, one of two newcomers elected at Quincy, provided one of the election's biggest surprises.
