Republicans Ben Carson and Carly Fiorina and Democratic Sen. Bernie Sanders have gained significant ground in their parties’ presidential primary races in recent weeks, the latest Wall Street Journal/NBC News poll finds.
Former Secretary of State Hillary Clinton and celebrity real-estate developer Donald Trump continue to lead the fields for their parties’ nominations. But Mr. Trump is now essentially tied with Mr. Carson, and significant movement has occurred among candidates just behind them.
Mr. Carson is the preferred pick of 20% of GOP primary voters, compared with the 21% who favor Mr. Trump. Behind them are Mrs. Fiorina and Florida Sen. Marco Rubio, both with 11% support. Other Republicans register single-digit support.
In the prior Journal/NBC News poll, conducted in mid-July, Mr. Carson had only 10% support, compared with 19% for Mr. Trump. The retired neurosurgeon overtakes Mr. Trump in the new survey, conducted Sept. 20-24, when voters’ first choice is combined with their second.
