The NBC News/Wall Street Journal poll released Sunday morning found 21 percent support from Republican primary voters for Trump and 20 percent for Carson.

Carson's support has doubled since July, when he attracted !0 percent in a similar poll.

Carson said Sunday that the poll “reflects what we’ve been seeing out on the road, just tremendous crowds but enormous enthusiasm.”

“And I think it says a lot for the American people, because it means that they’re not necessarily listening to the pundits, that they’re starting to think for themselves,” he added on ABC’s “This Week.” “And that, I think, is what it’s going to take to get us off of this inexorable track toward destruction that we’re on.”
