"The Primary"

"Debates alone rarely move poll numbers in big ways, and Trump continues to lead the crowded field with 29 percent of Republican and independent voters who lean Republican saying they would cast their vote for him. Ben Carson and Carly Fiorina remain on an upward trajectory, now filling in the second and third spots. Jeb Bush is holding steady at 8%, about the same level of support he's seen since April in NBC News/SurveyMonkey polling....

However, nearly a third of Republican voters now say that they expect Donald Trump will be the eventual nominee."...

"The NBC News Online Survey was conducted online by SurveyMonkey from September 16-18, 2015 among a national sample of 5,113 adults aged 18 and over. Respondents for this non-probability survey were selected from the nearly three million people who take surveys on the SurveyMonkey platform each day. Results have an error estimate of plus or minus 2.0 percentage points. A full description of our methodology and the survey can be found here. 
 
The survey was produced by the Data Analytics Lab of NBC News in conjunction with Penn's Program on Opinion Research and Election Studies with data collection and tabulation conducted by SurveyMonkey."
