By Emily Stephenson and Doina Chiacu MANCHESTER, N.H./WASHINGTON (Reuters) - Jeb Bush brought out his famous family four days before the crucial U.S. presidential primary in New Hampshire, tapping his mother on Friday to scold Republican front-runner Donald Trump over his use of profanity and treatment of women. In a last ditch attempt to make a mark on a Republican primary campaign he was supposed to own, Bush lashed out at both Trump and U.S. Senator Marco Rubio, the one-time protege who has eclipsed Bush as the party's establishment candidate in the 2016 White House race. New opinion polls following Monday's Iowa caucuses showed Trump maintaining a wide lead in New Hampshire's primary next Tuesday with Rubio rising into second place in the state as Republicans battle for the nomination in November's presidential election.
