  • Donald Trump maintains his lead over the GOP presidential field, according to a new CNN/ORC poll
  • Jeb Bush comes in second place and Ben Carson in third place, the poll says

Washington (CNN) — Donald Trump has won his party’s trust on top issues more than any other Republican presidential candidate, and now stands as the clear leader in the race for the GOP nomination, according to a new CNN/ORC poll.

The survey finds Trump with the support of 24% of Republican registered voters. His nearest competitor, former Florida Gov. Jeb Bush, stands 11 points behind at 13%. Just behind Bush, retired neurosurgeon Ben Carson has 9%, Florida Sen. Marco Rubio and Wisconsin Gov. Scott Walker 8%, Kentucky Sen. Rand Paul 6%, Texas Sen. Ted Cruz, former tech CEO Carly Fiorina and Ohio Gov. John Kasich all land at 5%, with former Arkansas Gov. Mike Huckabee rounding out the top 10 at 4%.

Trump is the biggest gainer in the poll, up 6 points since July according to the first nationwide CNN/ORC poll since the top candidates debated in Cleveland on Aug. 6. Carson gained 5 points and Fiorina 4 points. Trump has also boosted his favorability numbers among Republicans and Republican-leaning voters, 58% have a favorable view of Trump now, that figure stood at 50% in the July survey.

These nationwide findings follow recent polling in Iowa and New Hampshire showing Trump also leads the Republican field in those two key early states.

Bush, who held the top spot in the field in most CNN/ORC polls on the race between last fall and Trump’s entry into the race in June, has seen his favorability ratings drop alongside his standing in the contest. Overall, 56% hold an unfavorable view of the former Florida governor and 42% of Republican voters have a negative impression. That’s an increase in negative views among all adults (up from 43% since July) and among Republican voters (up from 34% unfavorable).

While Kasich and Fiorina remain largely unknown nationally, those Republicans who do have an opinion of these two — both widely seen as debate standouts — tend to tilt positive. Fiorina has a 45% favorable to 11% unfavorable rating among Republican voters, with 43% unable to rate her, while Kasich’s is 32% favorable to 20% unfavorable, with 49% unable to rate him.

The poll suggests those behind Trump love him: He holds a 98% favorability rating among his supporters. But those Republican voters who aren’t supporting Trump are skeptical that he would help the party. Most Republicans (58%) say the party would have a better chance to win in 2016 with someone else at the top of the ticket, including 72% of those who don’t currently back the businessman.

Still, Trump has quickly won the trust of Republican voters on several top issues. According to the poll, 45% say they trust Trump more than any other Republican candidate on the economy — up 25 points since June, 44% say they trust Trump over the others on illegal immigration — up 30 points since June — and 32% trust him most to handle ISIS, no other candidate comes close on any of these issues.
