A new CBS/New York Times poll shows that Donald Trump has lost his national lead among Republican presidential candidates, with Ben Carson surging ahead of the real-estate mogul. Carson is now the choice of 26 percent of Republican primary voters surveyed, beating Trump’s 22 percent. Sen. Marco Rubio is a distant third place with 8 percent, while Jeb Bush and Carly Fiorina are tied at 7 percent.
