On the campaign trail and beyond, there may be no larger caricature of New York City than Donald J. Trump.br The affiliation has proved problematic for Mr. Trump as he seeks the Republican presidential nomination.br In Iowa, Senator Ted Cruz of Texas took aim at Mr. Trump’s “New York values,” playing on the city’s reputation for secularism and liberal politics.br At home, top Democrats have disavowed Mr. Trump, calling his campaign a betrayal of the city’s inclusive identity.br But with the Iowa caucuses completed, Mr. Trump’s image as a populist strongman from Manhattan may find more receptive audiences.br In New Hampshire, the next state to vote, on Tuesday, Mr. Trump has led the polls by comfortable margins, and supporters there say there is nothing distasteful or suspicious about their candidate’s political persona.
