HUMPHREY LEADS M'GOVERN IN OHIO FOR VOTE TUESDAY
April 30: (Dem Aspirants' Activities) Sens Humphrey and McGovern appear to be in close contest for May 2 Ohio Dem Pres primary; strategists for both men agree that Humphrey is leading but disagree whether gap between 2 men is growing narrower or wider; withdrawal of Sen Muskie altered race from what was expected to be 3-way race to 2-way contest; McGovern, since his victory in Mass Dem Pres primary, has devoted all his time to Ohio, most significant of 4 primaries, Ala, Dist of Columbia, Indiana and Ohio, set for May 2; Humphrey has campaigned in Indiana, where he is pitted against Gov Wallace while Sen Jackson has been campaigning in Ohio since Apr 14; ex-Sen McCarthy has delegates entered in Ohio but has not actively campaigned; Muskie delegates remain on ballot but are given virtually no chance to win; Ohio Dem Party exec J E Jones says he thinks 20 delegates remain up for grabs and that favorite-son slates for Cleveland ex-Mayor Stokes and Repr Hays will probably share remaining 13 delegates; Stokes' slate is unopposed in Cleveland; Ohio Gov Gilligan and most of state's other Dems backed Muskie but Jones and official party machine has remained neutral; Humphrey is now seeking to get support of UAW, which backed Muskie; in Repub primary, Pres Nixon is facing only token opposition
