Sen. Ted Cruz has surged in the 2016 GOP presidential primary contest, consolidating support from the party’s most conservative voters and emerging as a leading alternative to businessman Donald Trump, a new Wall Street Journal/NBC News poll finds.
The latest poll, coming after a tumultuous month of international and domestic terrorism, found Mr. Trump tops in the GOP field, with Mr. Cruz in second place. The Texas senator appears to be benefiting from the sharp decline in support for Ben Carson, a retired neurosurgeon who led the pack in Journal/NBC News polling six weeks earlier.
The poll also showed a substantial lead for Hillary Clinton over her main rival for the Democratic nomination, Sen. Bernie Sanders, although the gap has narrowed.
Until recently, Messrs. Trump and Cruz have refrained from attacking each other, saving their barbs for other rivals in the crowded Republican field. But with a separate poll showing Mr. Cruz rising to first place among likely Republican caucusgoers in Iowa, he has increasingly come under direct and pointed attack from Mr. Trump, suggesting a messy new chapter in the GOP campaign on the eve of a nationally televised debate from Las Vegas on Tuesday night.
