In the latest snapshot of an unpredictable Republican primary season, Ben Carson has minimized Donald Trump’s lead to just 5 points, according to the latest NBC News online poll conducted by SurveyMonkey. These two “outsider” candidates are the only contenders with double-digit support among Republican and Republican-leaning independent voters. The next tier of presidential candidates is led by Marco Rubio at 9%, followed by Carly Fiorina and Ted Cruz who each have 6% of support, and Jeb Bush at 5%.

Helping to shore up Carson’s level of support are white evangelical Republican voters (including independents who lean Republican). Carson, a Seventh-Day Adventist, is now supported by 33% of white evangelicals, up from 20% in September, and outpacing Trump among evangelicals by 10 points. This is an essential voting bloc in the early caucus state of Iowa, where white evangelicals made up 56% of Republican caucus voters in 2012. That year, 33% of Iowa’s white evangelicals supported Rick Santorum, essentially handing him the narrowest of victories over Mitt Romney (who had the support of 14% of white evangelicals).

Republican voters who identify as “very conservative” are another group of significant importance in Iowa. Nearly half – 47% – of Iowa caucus goers identified as “very conservative” in 2012 and they voted 35% -14% for Santorum over Romney. Nationally, the NBC News online poll found Trump and Carson with nearly even support among those who identify as very conservative – 28% for Trump and 25% for Carson.
