When Iowa Republicans are asked who they would support in their local caucus, Ben Carson (23%) and Donald Trump (23%) tie for the top spot. The next tier of candidates includes Carly Fiorina (10%) and Ted Cruz (9%), followed by Scott Walker (7%), Jeb Bush (5%), John Kasich (4%), Marco Rubio (4%), and Rand Paul (3%). The last two Iowa caucus victors, Mike Huckabee and Rick Santorum, each garner 2% of the vote. None of the other six candidates included in the poll register more than 1% support.
“These results mark a significant shake-up in the leaderboard from Monmouth’s Iowa poll taken before the first debate,” said Patrick Murray, director of the independent Monmouth University Polling Institute in West Long Branch, NJ. “Carson and, to a lesser extent, Fiorina have surged, while Walker has faded into the background.”
In mid-July, Walker was the front runner in Iowa, with Trump and Carson following behind. Since then, Walker’s support has dropped by 15 points, while Carson’s has increased by 15 points and Trump’s by 10 points. Support has also increased for Fiorina by 7 points since Monmouth’s last Iowa poll.
Only 12% of likely Republican caucusgoers say they are completely decided on which candidate they will support in February. Another 42% have a strong preference now but are willing to consider other candidates, 27% percent have a slight preference, and 20% say they are really undecided even if they are able to name a choice now. Just 1-in-4 voters (25%) say they have their choice narrowed down to one or two candidates, while most (54%) say they can see themselves caucusing for any of 3 to 4 candidates currently in the race. Another 17% say they are realistically considering giving their support to 5 or more candidates in field.
Among voters who say their current decision is strongly locked in, Trump leads with 30%, compared to 22% for Carson. Among those who say they only have a slight preference or are up in the air, 25% support Carson and 16% back Trump.
“Trump’s support is currently more solid than Carson’s, but Iowa voters are still considering quite a few candidates before they come to a final decision,” said Murray.
Iowa GOP caucus goers say that, regardless of who they support in the primary, the country needs a president from outside of government who can bring a new approach to Washington (66%) rather than someone with government experience who knows how to get things done (23%). Among those who prefer an outsider, more than two-thirds are backing one of the three candidates who have never held elected office – Trump (32%), Carson (26%), or Fiorina (13%). However, even among those who say the country needs someone with government experience, 30% are currently supporting one of these three candidates.
Looking at the fundamental strengths of leading candidates, Iowa Republicans now hold an almost universally positive opinion of Ben Carson at 81% favorable to just 6% unfavorable, compared to 63% favorable and 11% unfavorable in July. Carly Fiorina has also seen her numbers improve to 67% favorable and 8% unfavorable, up from 44% and 10% in July. John Kasich’s name recognition has also gone up but the gap between his positive and negative ratings remains similar at 32% favorable and 23% unfavorable, compared to 24% and 17% in the prior poll.
Donald Trump’s rating has ticked up slightly – now standing at 52% favorable and 33% unfavorable, compared to 47% and 35% in July – while the ratings for Scott Walker and Jeb Bush have taken a dip over the past month. Walker’s rating is now 64% favorable and 16% unfavorable, compared to 73% and 9% last month. Bush’s rating is now 32% favorable and 51% unfavorable, compared to 40% and 42% last month. Ted Cruz’s rating of 58% favorable and 21% unfavorable is similar to the 53% and 17% rating he held last month.
The poll also identified candidate support among key groups of GOP caucus goers, including:
- Tea Party –Trump leads Carson 27% to 22% among Tea Party supporters, with Cruz at 16%. Among non-supporters of the Tea Party, Carson takes a 25% to 19% lead over Trump.
- Ideology – Very conservative voters split their vote among Carson (24%), Trump (23%), and Cruz (16%). Somewhat conservative voters are most likely to back either Carson (25%) or Trump (23%). Moderate to liberal voters prefer Trump (26%), followed by Fiorina (18%) and Carson (17%).
- Evangelicals – Evangelical voters favor Carson (29%) followed by Trump (23%). Non-evangelical voters prefer Trump (24%), Carson (18%), and Fiorina (13%).
- Gender – Men prefer Trump (27%) over Carson (17%), while women prefer Carson (30%) over Trump (19%).
“After more than a month of Trump winning virtually every Republican demographic group, we’ve finally got a little variation in voting blocs to talk about,” said Murray.
Hawkeye State Republicans are divided on whether their final decision about who to support in the Republican primary will come down to the candidate’s positions on the issues (45%) or their personal qualities and experiences (45%).
