Another poll gives Donald Trump a big lead in the Republican presidential race, and this one shows the New York businessman topping the 30% mark.

Trump scores 32% in the new CNN/ORC Poll, with another outsider — retired neurosurgeon Ben Carson — in second at 19%.

“Together, these two non-politicians now hold the support of a majority of Republicans and Republican-leaning independents, and separately, both are significantly ahead of all other competitors,” CNN reports.

No other Republican tops double figures in the new CNN survey.

Jeb Bush is third at 9% — down four points since August — followed by Ted Cruz (7%), and Mike Huckabee and Scott Walker (5%).

All the other Republican candidates finished at 3% or less.

CNN released the poll less than a week before Wednesday’s second Republican debate, which the cable news network is sponsoring.

In analyzing the poll, CNN reports:

“Trump’s gains come most notably among two groups that had proven challenging for him in the early stages of his campaign — women and those with college degrees. While he gained just 4 points among men in the last month (from 27% in August to 31% now), he’s up 13 points among women, rising from 20% in August to 33% now. Trump has also boosted his share of the vote among college graduates, increasing his support among those with degrees from 16% in August to 28% now. Among those without degrees, he stands at 33%, just slightly higher than the 28% support he had in August.”
