With four days before the Iowa caucuses, Donald Trump has pulled ahead of Ted Cruz in the Hawkeye State and holds commanding leads in New Hampshire and South Carolina.
Among likely GOP caucus-goers, Trump leads Cruz in Iowa, 32 percent to 25 percent, according to NBC News/Wall Street Journal/Marist poll. Marco Rubio is in third with 18 percent, followed by Ben Carson at 8 percent. Jeb Bush is at 4 percent in the Iowa poll.
The results mark a shift in opinions from just a few weeks ago, when Cruz held a 4-point lead over Trump.
