The far right in France had a big win this month, crushing the party of President Emmanuel Macron in elections for the European Parliament. But the results did not affect France’s government at home — until Mr. Macron changed that. Roger Cohen, the Paris bureau chief for The Times, discusses the huge political gamble Mr. Macron has taken, which has brought the far right closer than ever to gaining real power in France. Guest: Roger Cohen, the Paris bureau chief for The New York Times.
