Trump Surges in Polls

Republican presidential front-runner Donald Trump is building on his national lead among GOP voters, according to a New York Times/CBS News poll released Thursday morning. But many voters expressed fear or concern at the idea of a Trump presidency -- or a Hillary Clinton one.

Donald J. Trump occupies his strongest position yet in the race for the Republican presidential nomination, yet nearly two-thirds of American voters say they are concerned or frightened about the prospect of a Trump presidency, according to the latest New York Times/CBS News nationwide poll.
