"The poll of likely Iowa caucus-goers finds Trump with 25% support, Carson 23%. Those two are well ahead of their nearest competitors, Sens. Marco Rubio (13%) and Ted Cruz (11%). Behind this top tier, former Florida Gov. Jeb Bush tops the remainder of the field with 5%, businesswoman Carly Fiorina and Louisiana Gov. Bobby Jindal each hold 4%, New Jersey Gov. Chris Christie has 3%, South Carolina Sen. Lindsey Graham, 2008 Iowa caucus winner Mike Huckabee, Ohio Gov. John Kasich and Kentucky Sen. Rand Paul each have 2%, with the rest at less than 1% support....  
........

Among those who say they definitely plan to attend the GOP caucus and are more interested in news about the caucus than any other news (a group that makes up roughly 7% of all Iowa adults), the race looks about the same, with Trump holding a narrow edge over Carson, 31% to 24% (within the margin of error for a sample of that size), with Cruz at 14% and Rubio at 10%.

Overall, Trump continues to have a committed base of supporters in Iowa. Among those who say they have definitely decided who they're going to support, it's 39% for Trump to 22% for Carson with 14% backing Cruz and 8% behind Rubio. People who say they are "leaning toward" a candidate or "still deciding" break 24% Carson to 19% Trump, with Rubio (15%) and Cruz (9%) trailing.

Carson's strength in Iowa is boosted by his support among white evangelical Christians. Among that group, 31% say they back Carson, 20% Trump, 15% Cruz, 11% Rubio. Jindal runs in fifth place among this group with 7% support. Among those likely GOP caucus-attendees who are not white evangelical Christians, 28% back Trump, 17% Carson, 15% Rubio and 7% each for Cruz and Bush.

On the issues, Trump maintains huge leads as the candidate who would better handle the economy and illegal immigration, increasing his advantages on both issues compared with CNN's survey in August. The real estate mogul is less dominant but still ahead of the rest of the field on foreign policy, and runs about evenly with Carson on who would best handle government programs such as Medicare and Social Security. Carson holds the lead on handling social issues....

All told, Trump is seen as the party's best chance to win the White House by about a third of Iowa Republicans: 33% think Trump has the best shot at winning the presidency, 25% say Carson does, 17% Rubio. Just 8% name Cruz and 6% Bush. Further, 27% say Trump is most likely to be an effective president, topping Carson at 20%, Rubio at 13% and Cruz at 12%....

The CNN/ORC Poll was conducted by telephone October 29-November 4 among 2,009 adult residents of Iowa, including interviews with 548 likely Republican presidential caucus-goers and 498 likely Democratic presidential caucus-goers.
