MILWAUKEE (Reuters) - Donald Trump tried to put a difficult week behind him and rally his supporters on Monday ahead of a crucial Republican presidential contest in Wisconsin, where he faced the unfamiliar position of underdog.
Polls show the Republican front-runner trails U.S. Senator Ted Cruz of Texas in the Midwestern state, where a loss on Tuesday could dent the New York billionaire' s aura of inevitability and make it harder for him to win the 1,237 delegates needed for the party's nomination for the Nov. 8 election.
