In an effort to insure that Democratic candidates don't "destroy each other politically and waste energies and resources by competing against each other in the Massachusetts primary," the Mass Caucus '72--a newly formed liberal group--will endorse one candidate this Saturday and urge others to unite behind their choice.

McCarthy Agrees

Caucus organizers expect between 2000 and 3000 people--about one-third of them students--to attend the Caucus convention at Assumption College in Worcester. Any Massachusetts resident who will be qualified to vote in the April 25 presidential primary will be given a vote at the caucus.

Every candidate and potential candidate has been invited to address the Caucus, but so far none has accepted. However, former Senator Eugene J. McCarthy (D-Minn.) and Rep. Shirley Chisholm (D.N.Y.) are urging their supporters to attend. McCarthy has announced that he will be bound by the decision of the caucus and will enter the Massachusetts primary only if he is their choice.

State campaign managers for New York Mayor John V. Lindsay, Senator Edmund S. Muskie (D-Me.) and Senator George S. McGovern (D-S.D.) have indicated that their candidates will not consider the Caucus's decision to be binding.
