Donald Trump now holds a double-digit lead over Republican opponent Sen. Ted Cruz in the 2016 presidential race, according to a new NBC News/Wall Street Journal national poll.
Trump is the first choice of 33 percent of Republican primary voters, the national survey found. Cruz was the preference of 20 percent of respondents, followed by Sen. Marco Rubio at 13 percent and pediatric neurosurgeon Ben Carson at 12 percent.
