In October 1967, a private meeting was arranged between Parrish and Bobby Kennedy by mutual friend and well-known Kennedy photographer, Stanley Tretick. She begged Bobby to run for president telling him that huge, influential organizations opposed to the war in Vietnam were ready to support him if he ran. Kennedy refused again and again, saying he could not oppose Lyndon Johnson, a sitting president. On November 30, Eugene McCarthy, a brilliant yet little-known senator, declared he would run against the war and challenge Johnson. Parrish was elected chair of his speaker's bureau and utilized STOP! to develop support for McCarthy. On March 12, 1968, McCarthy almost defeated Johnson in the New Hampshire primary winning 42% of the vote. On March 16 (four days later) Bobby Kennedy announced that he would run for president. Two weeks later, on March 31, Johnson declared that he would not run again for president. Parrish remained loyal to McCarthy and was elected a delegate to represent him in August at the 1968 Democratic National Convention in Chicago.
