The gold standard Iowa pollster, Selzer & Co—their caucus record is nothing short of amazing—is out with a new poll showing former President Donald Trump with a significant lead among likely Republican caucus-goers. He has 42 percent support, Florida Governor Ron DeSantis has 19 percent, and Senator Tim Scott has 9 percent. Former Vice President Mike Pence and former United Nations Ambassador Nikki Haley were tied at 6 percent, former New Jersey Governor Chris Christie registered 5 percent, entrepreneur Vivek Ramaswamy 4 percent, and all others at 2 percent or less.  

I have written about the Iowa caucuses and their history many times. A few reminders:

This post will present the state of play in the U.S. Senate races as of November 4. The data includes all polling available at 7:00 am Eastern; polls are released so frequently that it is impossible to analyze the situation without stopping.

Before we get to the survey numbers, though, we need to consider the environment in which these elections are taking place.

Polling is fundamentally broken, and political forecasting is broken as a result. As a result reporting on politics is broken and focuses on minor differences in polling, rather than discussing what the candidates believe and want to accomplish in office.

Some of the biggest misses in 2016 and 2020 came from what were once thought to be gold-standard pollsters. The most accurate pollsters turned out to be firms with right-wing associations like Trafalgar. The 2020 polling misses were not uniform—they were not as large in Nevada or Georgia—and no one is really sure why. There are various theories.

Let’s start with the data.

Ann Selzer commented on her latest Iowa Poll of the U.S. Senate race for the Des Moines Register and Mediacom: “It says to me that Franken is running a competent campaign and has a shot to defeat the seemingly invincible Chuck Grassley — previously perceived to be invincible.”

The gold-standard pollster‘s statement will shock many political observers. Forecasters that issue ratings on Senate races have uniformly discounted any chance that Chuck Grassley will lose. This race is simply not on the national radar. Since 2016, Iowa has seemingly marched inexorably toward becoming a red state.

The U.S. Supreme Court released its decision in Dobbs v. Jackson Women’s Health on June 24. Overturning Roe v Wade caused a political earthquake.

I created this table to show the magnitude of the change in the generic ballot (which asks voters whether they plan to support a Democrat or a Republican for Congress). My averages differ from sites like FiveThirtyEight and RealClearPolitics, because I compare results across time from each pollster, rather than averaging all polls at a point in time. (I will explain why this matters at the end of this article.)

Asking if Senator Chuck Grassley could lose seems absurd. He has received more than 60 percent of the vote every time he has been up for re-election, beginning in 1986. He represents the opposition party at a time when President Joe Biden’s approval rating is below 40 percent.

The Des Moines Register has not released Biden’s approval numbers for their latest Iowa Poll by Selzer & Co, but in March they found Biden’s approval in Iowa was 35 percent, with 59 percent of respondents disapproving. Given the national trends, it is unlikely that the president’s numbers have improved in Iowa since then. Moreover, Republicans have made big gains in Iowa since President Barack Obama carried the state in 2012.
