In a Pew Research Center poll released Friday, Trump leads the pack with 25% support among likely Republican voters nationally. That's 9% above the next-closest competitor, retired neurosurgeon Ben Carson, who garnered 16% support in the poll.

Hewlett-Packard CEO Carly Fiorina and Sen. Marco Rubio (R-Florida) tied for third place with 8% support.

Trump is also still dominating among almost every demographic group surveyed — including women, young people, and those who earn more than $75,000 annually. There are only two exceptions — college graduates and voters who report attending church weekly, voters with whom he loses slightly to Carson.
