Bush stumps in Massachsetts for GOP's Senate candidate

Vice-President George Bush brought the Republican presidential campaign Thursday to heavily Democratic, largely Italian-American East Boston with an enthusiastic endorsement of Raymond Shamie, his party's newly nominated candidate for US senate. Praising the Bay State conservative industrialist for standing ''shoulder to shoulder'' with President Reagan in support of ''programs for peace and prosperity,'' Mr. Bush asserted that the big issue in the senatorial campaign is ''who can do the most for Massachusetts.''
