[The Suffolk University Iowa poll](http://www.suffolk.edu/news/60760.php#.Vco%5FOp1VhHy) found Trump in first place in the first-in-the-nation contest with 17%, followed by Scott Walker with 12% and Marco Rubio with 10%. Trump is currently leading most national polls. But the Suffolk University poll found that Trump’s lead was narrower among voters who had watched the first Republican debate on Aug. 6\. Among those viewers, Trump and Walker were tied at 14%, while 55% said they were less comfortable with Trump as a candidate after watching the debate. Instead, debate viewers said that Rubio and Carson were the most impressive candidates. Trump has [come under fire](http://time.com/3989656/donald-trump-redstate-gathering/) since the debate for attacking Fox moderator Megyn Kelly. The survey was conducted with 500 likely Iowa presidential caucus voters and has a margin of error of +/-4.4 percent. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/3992994/donald-trump-iowa-poll/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/3992994/donald-trump-iowa-poll/"},"headline":"Here's Which GOP Candidate Is Ahead in Iowa","datePublished":"2015-08-11T19:01:42.000Z","dateModified":"2026-02-22T10:05:23.719Z","description":"A new poll shows that Donald Trump is leading the Republican field in Iowa, but he's not who Iowans thought won the first debate.","url":"https://time.com/3992994/donald-trump-iowa-poll/","keywords":["2016 Election","2016 Election topic","Sen.
