Public Policy Polling has a new poll out on the Iowa governor and U.S. Senate races. Click here for Tom Jensen’s summary and here (pdf) for full results with questionnaire and cross-tabs. PPP surveyed 668 registered Iowa voters between July 5 and 7, producing a statistical margin of error of plus or minus 3.8 percent.

Highlights: both President Barack Obama (46/50) and Governor Terry Branstad (45/46) are slightly underwater on approval ratings. However, Branstad has double-digit leads over Senate Majority Leader Mike Gronstal, State Senator Jack Hatch, and State Representative Tyler Olson. Lieutenant Governor Kim Reynolds is much less known than Branstad and is tied with or barely ahead of the Democratic candidates in hypothetical gubernatorial match-ups.

In the Senate race, Democratic Representative Bruce Braley has higher name recognition than any of the Republicans and is more liked than disliked by Iowans who have an opinion about him (34 favorable/24 unfavorable). In head to head match-ups, he leads Matt Whitaker by 9 points, Sam Clovis, Joni Ernst and Mark Jacobs by 12 points, and David Young by 13 points.

Any relevant comments are welcome in this thread. I wouldn’t read too much into horse race polling 16 months before the election, especially since none of the Senate candidates are particularly well-known, nor are the Democrats running for governor. Braley polls about the same against any of the Republicans now, but as the campaign progresses I believe it will become apparent that certain GOP candidates have more upside than Clovis, for example.
