According to the poll, that represents a 10-point surge for Carson, a retired neurosurgeon, since late August, and a 4-point drop for Trump.

It's the second poll in as many days showing Carson knocking off the billionaire businessman from the top spot in the Hawkeye State, where the real estate tycoon has led for three months. 

Carson beat Trump 28 to 20 percent in a Quinnipiac University Poll released Thursday.

The results suggest social conservatives in Iowa, long a force in the state’s caucuses, may be gravitating toward Carson.
