President Obama said in a radio interview airing on Monday that Donald J. Trump, a leading contender for the Republican presidential nomination, is exploiting the resentment and anxieties of working-class men to boost his campaign. Mr. Obama also argued that some of the scorn directed at him personally stems from the fact that he is the first African-American to hold the White House.
Demographic changes and economic stresses, including “flatlining” wages and incomes, have meant that “particularly blue-collar men have had a lot of trouble in this new economy, where they are no longer getting the same bargain that they got when they were going to a factory and able to support their families on a single paycheck,” Mr. Obama said in the interview with National Public Radio.
