Cambridge's all-Democratic City Council voted, 5-1, yesterday to endorse Rep. John W. McCormack (D-Mass.), House majority leader, as favorite-son candidate for President. McCormack was proposed as an alternative to Adlai Stevenson in the April 24 State primary.

Mayor Edward J. Sullivan and Councilor Joseph A. De Guglielmo '29, who are running as delegates to the Democratic National Convention, abstained from voting.

The only councilor to vote against the proposal, Mrs. Pearl K. Wise, objected that it was "unfair" for the Council to go on record for any candidate. "It means we are urging the voters of Cambridge to support our choice," she stated.

De Guglielmo explained that the resolution placed him in an "awkward position." He said that "although I respect McCormack and will probably support him if he is a candidate, I do not want to be constrained by any choice I make at this time."

No Embarrassment

Sullivan, originally a sponsor of the endorsement, withdrew his support after De Guglielmo's statement. "As an unpledged candidate for the state delegation," he maintained, "I cannot vote for McCormack."

"Nobody should be embarrassed to back McCormack as a presidential candidate," according to Councilor Edward A. Crane, one of the resolution's sponsors. "No councilor who voted for the proposal would have to vote for McCormack if he stopped being a candidate," he held.
